Colors

The Japanese have adopted about 80% of our names for colors. They use "Pink", "Orange", "Violet"..ect. When you see a color below without a Kanji it means they use the English name.

IRO		This Kanji means "Color".
Aka(i)		Red
Ao(i)		Blue
Midori		They also use the english "green" (Now you know where the Liquer called Midori gets it's name)
Kuro(i)		Black
Shiro(i)		White: Also known as "Haku"
Kiro(i)		Although it's not in English, there's no Kanji for Kiroi that I've ever seen. In fact, they spell it in Katakana. Karaoke is another Japanese word they use Katakana for. I don't know why.
Orenji		Oddly enough..orenji jusu = Orange juice...who knew?
Fuji iro		They usually say "Vio" or "Violet"...Fuji Iro is an old term.
Momo iro		Momo means "Peach". Old japanese word for pink. now they just use "Pink"
Cha iro		There is a kanji for this..its Tea Color.
Ha iro		again...an old word. They just say "Grey" now.

Japanese sentence structuring is Object first. A good trick is to speak it like Yoda...that's about the right arangement.
