This looks good. However, I would love if we could solve the issue with the base icon color at the Icons component level.

Same comment as in another PR. Here we should define whether the standard is to use the iconColor prop or go with this approach. Additionally, we might want to use this color as the base for the Icons component in general, to avoid repetition.
