Thanks for the constructive feedback.
Sounds silly but I'm kind of happy someone finally mentions the colors. I'm colorblind so my assumption was all the time, that the colors have to be awkward for normal people but no one ever said something like that.
But I can appease you, the color thing is an ongoing process and the actual colors are all but not final. I think I will look for a matching color palette and just use it instead of making it myself.
