Please also consider accessibility when designing your figure, so that your images can be easily understood by colour-blind and visually-impaired readers. Guidelines for preparing different image-types, including recommendations for colour palettes, colour contrast, image layout, and text accessibility.
Incorporating alt text (alternative text) when submitting your paper helps to foster inclusivity and accessibility. Good alt text ensures that individuals with visual impairments or those using screen readers can comprehend the content and context of your figures. The aim of alt text is to provide concise and informative descriptions of your figure so that all readers have access to the same level of information and understanding, and that all can engage with and benefit from the visual elements integral to scholarly content. Including alt text demonstrates a commitment to accessibility and enhances the overall impact and reach of your work.
Alt text is applicable to all images, figures, illustrations, and photographs.
Alt text is only accessible via e-reader and so it won’t appear as part of the typeset article.

One of the recommendations is to use a color blindness simulator. Having a color vision deficiency myself, I cannot judge whether these tools work well. Nevertheless, a trial-and-error based approach seems rather inefficient. Instead, the use of (a number of) default color blind friendly palettes would be much more straightforward. For instance, green and magenta colors are the default choice for the production of color blind friendly overlays of fluorescence images. Below, I discuss a number of color palettes that are suitable for coloring graphical elements in plots. I think that people with a color vision deficiency would benefit from the implementation of these palettes in software for data visualization....
