RGB (Red, Green, and Blue) is the color space for digital images. Whether it’s your website, social media images, or a piece of collateral that will be shared digitally, you’re going to want to use this color profile if your design is supposed to be displayed on any kind of screen.
This color profile uses red, green, and blue to create various colors. A light source within a device creates any color you need by mixing these colors and varying their intensity. This is known as additive color profile: all colors begin as black darkness and then red, green, and blue light is added on top of each other to brighten it and create specific colors.
Digital screens (like those utilized by computers, tablets, or phones) use these three colors in various combinations to create the images you see on your screen. Using a CMYK image on a digital screen could give you some unexpected results that make your colors seem inconsistent.
JPG or JPEG files are a common RGB file-type and have a nice balance between file size and quality, and they’re readable almost anywhere across devices.
PSD files are the native documents created in Adobe Photoshop. This type of file contains layers that make modifying the image much easier to handle.
PNG files support transparency and are better for graphics that need to be superimposed over others.
Along with the SVG (Scalabale Vector Grahpics), JPG and PNG profiles are perfect for website optimization.
A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value.
If all the components are at zero the result is black; if all are at maximum, the result is the brightest representable white.
