Why are there no S-JIS lyrics?
There are tons of Japanese lyric databases on the internet like Utamap, not to mention the seas of Japanese fan sites that post them. If you can read Japanese well enough to want S-JIS lyrics, you can navigate these sites with ease. Since this site is built for the non-Japanese speaking fandom, there's no real need for kanji here aside from titles which I have put up for reference.

What is all this color business it makes no sense.
It's pretty straight forward - each page shows the colors I've associated with each group member. Parts they sing solo are in their color, parts where just a few members are noted like this: [Name/Name/Name], and parts that are sung by the entire group are left black. If I add anything else, it'll be noted on that particular page.

Hey, those aren't the official colors of (insert group here)!
The main groups I think this comes up for are Arashi and NEWS. I started color-coding Arashi lyrics way back before they had a set of "official" colors. I based the colors at the time off of the colors they used on D/G no Arashi. Since there are already so many done, it would take too much time to go back and change them. Same with NEWS - I started before they had official colors, so I can't change them now. Otherwise, I try to keep the colors the same as the official colors unless there's a special group like J-FRIENDS and some member colors overlap.

Where's the Hikaru Genji and Go Hiromi? What about 4Tops?
Currently this site only hosts debuted and active Johnny's groups. Once all of the active artists's discographies are completed and a significant number of their lyrics up, I may go back and add past artists that either disbanded or left JE. I have no plans to ever add lyrics for Junior groups, past or present.
