Lait Sunscreen

skin multicolor on half my body?

I am 25. since I remember, if you draw a virtual vertical line on my body, the skin on my left is white but the skin on my right side has irregular darker patterns, the patterns are on half my torso front and back, one arm an one leg (no patches on or around the fingers). the patches (look cafe au lait color) get darker when exposed to the sun without sunscreen. They don't hurt or anything, they are NOT contagious but they are ugly. Does anybody know what i'm talking about ? does this condition have a technical / medical name ?
Crh08 : I looked at the 1st link you sent, that's much darker than my sports. the color is very close to the 2nd link you sent, but the patches are spread on a much bigger surface. none of them are on my face or the other half or fingers.
It's defintely NOT Vitiligo. it's sortof the opposite. patches are darker and not lighter. I don't have any on my fingers.

If they don't look like the picture above its a sort of birthmark.
i have the same thing! ; )
