Color, AI (Artificial Intelligence), and the User

At Venture Cafe's Artificial Intelligence, Charis Loveland described how AI was used to select options to display to customers based on their searches. She described how color names are mapped to numbers -- a decimal point a bunch of numbers behind it -- so that the app could calculate how similar colors are to one another.


My history with color came flooding back to me. In high school art class, colors were combinations of red, blue, and yellow. When I worked on image processing as a software engineer, colors were light-based combinations of red, green, and blue (RGB). For printing, colors were combinations of cyan, magenta, yellow, and black. Doing web development, there were 216 "web safe" colors that would display the same on any monitor. Rarely would you use their names; but instead use a hexadecimal number to specify a color.


In Charis Loveland's presentation, the color examples were different shades of red: scarlet, magenta, cherry, maroon. I suspect the name-to-number mapping came from Pantone ® .


In my sketchnote of her talk, I originally used blue for the dresses. In the video from Procreate, see the dress colors change from blue to red to match her talk. Later in the video, see how I changed the background to work better with other elements.


When I draw I think about who will be viewing the image. For the colorblind, I use colors that are different shades so if they can't differentiate, say between red and green, they can differentiate by which one is darker. To test if there is enough contrast, I use an image editor or print preview to see how the image looks in gray scale. If the contrast is still there, the image will work for the colorblind.
