Color mixer or Color Blender is one of many browser tools available on the ColorDesigner website. It allows users to blend two or more colors in different quantities and see the color that the mixture will result in after blending as well as the proportions and colors used to create it. In addition to displaying the resulting color, the Color Mixer also allows the user to display and use colors in different modes such as HLC, HSL, and LAB as well as RGB and LRGB.

Color Mixer page greets the user with a basic selection of primary and secondary colors which the user can then mix and blend freely as they see fit. Start by choosing colors that you want to blend. You can either chose your colors from the already existing shades offered on the website or add your own custom color that you created. Once you have all the colors that you want to mix, add each color in the desired quantity. The resulting color will be displayed along with the proportions of colors used for the mixture and keep changing based on the colors that the user adds. Keep mixing colors until you are satisfied with the result. Your color will also be displayed in different modes and formats, so you can easily recreate them at a later point in time.

Users can add custom colors of their choosing by using either the Color Picker which will display the color palette and allow the user to choose the desired color by clicking on it from the color wheel, or by entering either the colors Hex Code, the RGB decimal code, or the values of the hue, saturation, and brightness. Additionally, the user can swap to the swatches tab which will, in turn, display the color swatches for both primary and secondary basic colors. From there, once the user settles on the basic color, he or she will be able to pick one of the many shades of the desired color which will be displayed on the screen. Once the user is happy with their choice, they can confirm their selection, and their color will be added to the main color selection from which they can decide on the mixing quantity.

Color mixture is a colloquial term denoting mixture of direct and indirect color stimuli: lights or colorants (dyes and pigments) by physical combination, different stimuli appearing in rapid succession in the field of view, or stimuli so small that they cannot be individually resolved by the visual system. In addition, it refers to the implied mixture of percepts in the mind.

All forms of color mixture rely ultimately on subjective judgments of identity or difference of color, i.e., on the operation of the color vision apparatus of color-normal observers. However, at this time there is no solid neurophysiological theory of human color experience. A form of purely subjective color mixture was proposed in the late 19th century by Ewald Hering and is based on six perceptual primaries, two achromatic: white and black, and four chromatic: yellow, red, blue, and green (Hering, 1964). All natural color percepts of the color-normal observer are considered to be the result of a single, or mixtures of two adjacent of these chromatic percepts, alone or together with one or both of the achromatic percepts.

Each monochromatic light of the spectrum causes a slightly different stimulation of the color vision system but only approximately 120 different hues can be distinguished. In addition there are some further 30 hues not appearing in the spectrum, but generated by mixture in various ratios of the two lights from the ends of the spectrum. Together they form the complete hue circle.

In 1704 Newton, in his book Opticks, expressed these results in a semi-quantitative, center-of-gravity-based hue circle (Figure 1) in which the result of mixture of all hue stimuli is light appearing hueless, or white, located in the center. White is also the result of appropriate mixture of hue stimuli diametrically opposed in the diagram as well as of innumerable combinations of three and more properly selected monochromatic lights. Thus, the diagram also implicitly demonstrates the fact of color metamerism, a term for the concept that certain different spectral combinations of lights result in identical percepts. The wavelengths of diametrically opposed pairs of lights, called complementary, have been investigated in detail in the second half of the 19th century by Hermann von Helmholtz and others and were found to vary somewhat by observer. The rules, or laws, of additive color mixture were defined in 1853 by mathematician Hermann Gnther Grassmann (mathematically formalized by D. H. Krantz in 1975)(Helmholtz, 1924; Krantz, 1975).

The best known practical examples of this effect are in image reproduction in books and newspapers (halftone printing) and on electronic display systems. But this process is also active when fabrics finely woven from differently colored yarns are viewed from a distance. This kind of color mixture was the impetus behind pointillist painting in post-impressionism (the best-known artist being Georges Seurat, 1859-1891), however with somewhat disappointing results because the viewer rarely has sufficient distance from the painting for the colored dots to fuse and if they fuse the image is often grayish because of hue cancellation.Halftone printing is not purely additive because the halftone dots on the paper are not always independent but often overlap more or less, resulting in a form of subtractive mixture in the areas of overlap. Figure 4 shows the enlargement of a portion of a halftone image, showing separate as well as overlapping dots of the three chromatic halftone primaries cyan, magenta, yellow, and black (CMYK). Complex algorithms are required to calculate the result of such combination of additive and subtractive mixture (Field, 2004).

The generally best known kind of color mixture is colorant mixture, the mixture of dyes and pigments. As mentioned, pigments are natural or artificial chemical compounds with selective reflectance or transmittance and absorption properties of light in the visible spectrum. Dyes impart specific light transmittance and absorption properties to liquids they are dissolved in or reflectance and absorption properties to substrates to which they are applied. The transmittance or reflectance properties are a non-linear function of colorant concentration. Figure 6 shows an example of the reflectance curves of a dye applied in different concentrations to a textile material. For solutions of dyes, the relationship between dye concentration, thickness of the transmitting layer, and light transmittance is approximately logarithmic, as determined by P. Bouguer (1698-1758) and A. Beer (1825-1863), known as the Beer-Bouguer law. For various reasons actual dye solutions frequently deviate somewhat from the law. The situation is more complex in case of reflecting materials. The corresponding laws have been developed by physicists P. Kubelka and F. Munk (1931) known as the Kubelka-Munk laws, and since then expanded by several authors. In case of dyes the material to which they are applied in addition to transmitting light also scatters light. Pigments themselves not only transmit but also scatter light to different degrees. As a result, the relationship between colorant, its concentration, and the reflectance function of a single colorant or its mixture with other colorants is complex and nonlinear. Both the Beer-Bouguer and the Kubelka-Munk laws are used extensively in technology for purposes of quality control and colorant formulation.

I'm trying to find an algorithm that will mix colors, based on a % amount. I'm working on an election project, and want to be able to assign each candidate in a race a different color, and then create a "resulting" color based on how much of the vote that candidate has gotten.

is close the question I'm asking - but potentially I need to be able to mix 3 or 4 or 5 colors together. I understand that this ultimately an incredibly complicated question - but I'm curious what the suggested method is for doing this on more than 2 colors. So, I might have:

Edit:So - after posting this message, I realized that what I was really trying to accomplish was basically PAINT color mixing. IN other words, I don't want LIGHT color mixing, I want to simulate what would happen with PAINT mixing - as that is the "predictable" result that I kept 'expecting' - and was having trouble getting.

which behaves VERY closely to what I'm trying to accomplish - and exposes a small "flaw" in my original idea. What is demonstrates is that even though I can mix up to 6 colors using this algorithm, the actual "data" is always broken down into the 3 primary colors.

From my research, it seems there isn't any one correct answer, but whatever seems to produce the most appropriate effect. Moreover, I don't think simply blending the colors would really indicate anything on an infograph. You'd be better off trying something like a really granular dither _photography_and_image_processing

The RGB colors system is bad for such calculation, because it does not work like we humans perceive colors. For example we just do not perceive yellow as a mixture of green and red.The first step is to convert your colors in a color space where you have a lightness coordinate and two coordinates for the color. This can be either HLS or CIELAB. HLS conversion is more simply, but coordinates in CIELAB represent better the human color experience. Equal distances in this color space are at least roughly equal distances in human perception.

In this color space you have coordidates L, A and B. L should be the same for all your colors. Your base colors should be on a circle around the gray-point, so they have the same distance, and no colors is stronger than the others. so you basically have a few points in the plane and need to calculate their weighted middle point of these points. The you convert this point back to RGB.
