All those pinks are extremely unnecessary for a builder such as Brickitect and yourself as they really limit the colorset to more useful, designated colors. Trust me, you will never need to use all those pinks, atleast in this specific colorset.
You only really need a cherry blossom-like pink, and a soft red for a second pastel pink color along with a deep purple and you should be set. Though this statement is purely based off my own building needs. If it's a colorset for your personal use, go for it.
I'd also recommend a nice dark or navy blue somewhere up in there. Greens need a lot more attention and variety as well. The more the greens, the better. Shoot for around 6-9 green colors if you can. No neon or overly vibrant colors.
The browns and greys are very nicely set up so nothing really to add there. also a good selection of tinted greys for stone masonry.
REMOVE THE COLORED GLASS. Frees up a ton of space for more useful colors. Again if you use them, then go ahead and keep them but personally I never find those useful.
Though if you like pixel art i would recommend making a specific colorset for pixel art because architectural/realistic colors and pixel art colors are not to be mixed up into one single colorset.
I'd link my colorsets if you would like a valid example but you and brick have used mine for a while now so I'm sure y'all already know them well enough lol
