"Technically you should do it with two hands instead of four" lol. It's so cool that you guys spoke three different languages in a three minute~ video. すごい!
You add an 'i' at the end of the color if it is used before the noun. For instance, Akai inu. If the color is after the noun, you do not add anything. For instance, Inu wa aka desu.
if I had a Japanese keyboard I would show you but oh for pete's sake forget it LETS DO IT ao = blue, aka = red aoi = blue (noun), akai = red (noun) basically what Creo
+Matthew K While Kan-ji comes from the Chinese Han-zi and are essentially the same, Kanji specifically denotes Japanese meaning and pronunciation. Kanji = Adopted Chinese Character for use in Japanese. Hanzi = chinese character.
There are more color names in Japanese, of course, but this video is very interesting because it gives the basic colors and the way you have to write the kanji.
