Custom item colors

[zantoku]

I love the app, particularly the dark mode. It's a feast for the eyes! However, on Wanikani I use a popular dark mode stylesheet (Wanikani Breeze Dark) that also changes the item colors, like so:

@var color radicals-color    "Radicals Color"            #3DAEE9
@var color kanji-color       "Kanji Color"               #FDBC4B
@var color vocab-color       "Vocabulary Color"          #2ECC71

That can make reviews in the app a bit confusing sometimes, esp. for single-kanji vocab items. It would be nice if the app supported setting custom colors for the item types.
