Yellow I guess. I don't know why, but I've noticed a lot of items/mascots I like/want to buy are yellow like yellow Kirby or a Yellow Switch lite. Pink is ok probably my second favorite color, especially if it's coral pink.
i’m most fond of monochrome colours but i also like various shades of pink (rose, flamingo, peony), blue (cadet blue, turquoise) and green (teal, fern, viridian, olive, pine green), too! :’^)
Honestly various greys - i really like charcoal grey and payne's grey I find it such a warm neutral colour that goes well with softer pastels (which I also adore) without feeling too stark or too cold against them uwu
