Yeah, it occurred to me, but I was worried about leaving the dark green-cyan behind too much. I'm really not a fan of too bright green, especially not the bright mint green like in the C64 palette. That's the first color I scrapped.
I'm also unsure about the red being so dark, but I kind of like it.
Still v13. Most of the useful colors with a clear identity are mid value, so that's where I wanted to concentrate. There's a bit of a hard edge there at the green, orange, grey though...
(I think Ptoing got the order slightly wrong btw)
There's obviously always going to missing colors, so I really need to do more empirical studies to see whats a good compromise. I need to do more mockups still.
Edit: Thanks for the mockups and feedback!
