My fat PS2 only displays black and white.

The only cables I have are component cables, but my TV only has composite inputs. I did the yellow/white/red, and there was no input at all…and when I put the green cable in the yellow hole, the sound and picture came up. Only the screen is in black and white. It’s not an issue with the TV screen since the other inputs have color, and this is the first time this has happened [also the first time I’ve hooked this PS2 up to this TV].

Do I need to just get dedicated composite cables?
