Oh yeah I do have a thought and you won’t like it: stop using color everywhere!
When I see a dropdown of departments in a company for example, all colored, I die a little inside.
Why would “IT” be red and “Accounting” green? When you look at your project, it looks like a rainbow, and colors don’t make sense anymore. You don’t see the overdue tasks anymore because all those “IT” red tag pop up. And any overdue tasks from accounting is fine, because accounting is green 
New request: remove entirely the default color palette for custom fields, and let people hand-pick colors if they really want them =)
