yeah!
for the fox, i've thought of their hair to be white except for their bangs and side hair being multiple colors like a very light grey, pale blue, and a vibrant dark blue. for their skin i've thought of very pale skin with a pink-ish tone. their ears in my mind would be white but the tips of the floof inside of it would be the vibrant dark blue of the hair. the eyes, patch on their cheeks and the bell earings would be the same gold color to contrast against all of the blues and greys. the outfit would mostly be white but the decorations would be golden or a soft blue!
for the deer one i've thought of their hair to be yellow, their skin to be a warm brown color. i've thought of their eyes to be a pink-ish red-ish color or the same gold color as the fox. their cheek patch would also be gold. their horns would be black and the tips would be pink. their outfit would mostly be a pale pink but the decorations would be gold as well!
( i'll try to draw my thoughts once i have the time to )
those are my ideas for the color palette, i hope that i'd inspire you for the color palette dsfdsfsdfsdsdf
