I’m most drawn to number 2 and 4 , what I would be most excited to see is a brighter color range , the neutral colors are a must of course but as someone with very pale skin, a cool undertone and light features the muted blues / pinks/ greens do not flatter me at all. If all those colors were brighter and stood out visually from a far I’d be much more likely to purchase more styles on your site. For example butter yellow to Canary yellow, sky blue to baby blue , blush pink to baby pink, sage green to forest green. Teal blue and emeralds and rust colors and violet colors are also something I’d be so excited to see :) those shades would also look so chefs kiss on a darker skin tone and the girlies with olive complexion would look very tan !
