I don't have favorite colors in general, it's too hard to deciiiiiiide.
In toys I like pink, purple, and silver best I think. Though I want an orange Zini Donut, and I like the green Emerald Explorer over the purple (and if I get an Amethyst, it's gonna be blue.) The majority of my collection is pink, though.
Well my favorite colors are seafoam green, light blue, and I suppose lavender (Simply because it goes well with the first two!) All of my toys that have the option I get in cool colors! I just think that they look nicer!
My 3 favorite colors are blue, purple, and pink. I tend to have a lot more pink and purple toys, but I ALWAYS try to get something blue when the color is available in a toy I like. Because I like purple second to blue, I tend to go for purple when color options are limited to pink and purple.
