I'm not sure I understand you about the clothing colors. If you didn't know, the 8 colors on the right are custom color slots which can be changed to anything you want by dragging the bars. You'll get similar options for hair and eye color when you find the "hair dye" and "contact lenses" items in-game.
Regarding updates, the developer posts weekly progress reports on his Patreon, along with periodic pre-release versions of the game. The version here on Itch is two months out of date.
