Another 4% of the population has all three types of cones (RGB), but the red or green cones may not be fully functional, making it more difficult to distinguish green/yellow and blue/purple combinations.Approximately 95% of the general population has normal color vision and would have full access to the original palette.Update 2: Now with accessibility! With the help ofĬolor Blindness Simulator and this page listingĬolor blindness frequencies, I’ve added a function that allows the user to choose what percentage of the population they are seeking accessibility for: The conversions between various color spaces are not exact, but in my experience they work well. I did this deliberately, to further differentiate the colors. Some of the color names (like blue or green) don’t match up to typical HTML or RGB conventions. The order of the colors is inspired by their frequency of appearance on all the world’s subway maps (yes, I did count them all!). I’ve arranged the “convenient” order so that if you want six colors, for example, just choose the first six. Without further ado, I present my own list of 20 simple and visually distinct colors, plus black and white. Not only that, there were no hex triplets, nor RGB nor CMYK values.Įvery list of colors that I found online suffered from the same problems. The orange yellow, purplish red, yellowish brown and reddish orange all seemed to blend together. Unfortunately towards the bottom of Kelly’s list things get a bit complicated. Surely I’m not the first person to have this issue, I thought. ![]() (Update: I went with repeating colors instead, numbering each line and making sure that same-colored lines were far from each other.) No matter what I did, some colors were too similar and could be easily confused. The challenge was to color-code 20 different rail lines for a metro system diagram, and I found myself spending an inordinate amount of time choosing the colors. In making my Roman Roads project, I came across a problem. Don't use more than 5 colors in a real line chart. The kind of map or chart color palette a practitioner should use depends on the data's characteristics.Note: This is just to test contrast.

The colors we use in maps and charts play a significant role in the effectiveness of our message. A common way to misrepresent information is an incorrect use of color or data visualization color palettes. Perhaps the tools made it easy to visualize data clumsily or produce an imbalance between aesthetics and understanding. We've all spent considerable time engineering data, conducting analysis, and preparing results, only to struggle with practical data visualization techniques and tools. Telling compelling stories with data can be pretty tricky. ![]()
