Yeah, we're seeking for variety of colors to be used in our building, keep in mind that you should probably include colors that are not vibrant so that our eyes won't be bothered. Honestly you should shorten the amount of colors in one row (greys and standards), meaning that you should remove some, as there are several colors appearing very similar to its neighboring colors.
Be sure that the rows are even, some players discourage rows that are too long and short because they don't want to deal with uneven scrolling. If you demand a way to even out your rows durjng your revision, try to find a way to include transparent colors in a row of opaque colors if they're closely related and if you have enough room to do so.
However, I do like the colors in rows 6 and 7, those are colors that players prefer to use. Please take note to Teneksi's and my constructive criticism, I assure you that it will help you revise this colorset. Good luck, friend!
