Hey @tomek! I took a look at our color.js file, and did notice that errorDark50 isn't used in any other components yet. I know the designs are using errorDark50, but thinking about it, it may be better to use

vibrantRedButton: designSystemColors.errorPrimary

My only concern with the primary color was how bright it may be and attention grabbing, but we already have components using the primary in our system. What do you think?

For me there's a value in distinguishing between error and destructive actions. So having different colors for them makes sense. But merging these also is an option.

I've checked how it looks like with an alternative color. It's indeed brighter. But compared to the older color, that button looks a little bit like it's disabled. (but only in comparison)

@ted is on vacation now, but I agree the darker color looks a little bit disabled in comparison. Personally, I think I'd prefer the brighter red

In the summary there's a screenshot with it - looks ok, I guess.
