Colors in Sindarin

Mae Govannen! I'm wondering what colors are in Sindarin. I tried looking up purple, but nothing came up. Nor did lavender or amethyst. Thank you for your help!

Here you go:

• S. nim adj. “white”
• S. fain “white, shimmering, shining”
• S. morn “black, dark”
• S., N. caran adj. “red”
• S., N. #rhosc adj. “russet, [N.] brown”
• S. luin “blue”
• ᴺS. [N.] ^elu adj. “(pale) blue”
• S., N. calen adj. “green; †bright”
• S. †laeg “green, viridis, green (of leaves/herbiage), fresh”
• S., N. baran adj. “brown, golden-brown”
• N., ᴱN. malen adj. “yellow”
• ᴺS. !melingarn adj. “orange, tawny”
• S., N. mith adj. “grey, light grey, pale grey”
• S., N. thind adj. “grey”
• Purple could be luingaran based off of ᴺQ. !luicarnë
