This time there’s a common theme with the links: color. 🎨 I’ve recently been subtly tweaking the colors of my blog, so I’ve (re)discovered these resources:

  • WebAIM accessibility checker. Check that the contrast between foreground and background colors is big enough. You don’t even need to be old or have bad eyesight to benefit from good contrast, as sometimes the external circumstances like a glare on your screen make the text hard to read if the contrast is not there. There’s really no excuse for bad contrast.
  • Name all the colors at Color Names.org. This is a fun effort to name all the 16,777,216 colors in the RGB color space. Almost a quarter of the colors have been named as of writing this. No need to register, just pick a color and think of a name for it! For example, the dark mode background color of this blog is called Oriental Popcornflower. 🍿💐
  • macOS has a built-in utility app called Digital Color Meter with which you can pick the color code of anything on your screen.
  • Finally, an infuriating optical illusion: these two faces are the same color! The illusion is based on a phenomenon called color constancy, where the surrounding context tricks our brain.
