that makes me very happy!! i have Strong opinions abt the animal emojis lol

as for colors, idk abt any official colors. if you mean their mics, those are chosen by the members. but i personally associate them with,

yg: black, browns & dark neutrals. cool deep blues/purples & cool tones overall. but sometimes gold or deep red & darker warms (like warm, rich browns), or a fire. black is the strongest, tho
jm: golds/yellows, pinks, oranges, white, and blues. some black. lighter colors with some richer, darker midtones mixed in. anything pastel or shimmery goes to him. peachy neutrals. gold or pink is at the top for him.
sj: pink, black, white, blue. cool gray or warm light neutrals. except black, lighter tones, including some pastels. he's the most neutral to me & shifts between warm/cool. that or he's like...christmas.
nj: all shades of green. brown neutrals & any nature-y neutral. white. light blues. he always has a lighter color balancing him out or is a lighter color. prob the most brown
th: green, purple, blue, brown. all deep but saturated, not dark. midtones. any of those colors combined with p much any other color makes me think of him, esp if they clash. but i associate him the most with green/purple
jk: red, black, silver, purple, esp pinkish purple. gray neutrals. and gray itself. cool tones. but overall, i associate him the strongest with red
hs: any bright, saturated color. yellow, red, and white esp. dark brown neutrals & warm neutrals. sometimes bright but cool tones. yellow is foremost for him, but only if it's bright. if not, red
