Color by tag - the color choices?

I’m just curious… who chose the tag colors? Is there a particular reason these colors were chosen? Is it a matter of making this most accessible for colorblind folks, or something? Are they actually just randomly chosen colors? I’m not trying to say anything negative about the color choices, they just make me very curious

They are random and you can change them to suit your taste or needs.

Open the tags window and click on the little color sample on the tag’s line. That will open the color/materials chooser to let you set a different color.
