as far as colour accuracy goes, the blonde one does't come out like that, its kind of a bland kind of sand colour. Kinda like the yellow/glodish stuff they put between bricks on houses in the UK :roll: . The dark brown and black ones are accurate though. I havn't ordered the others so I can't say.
PS. If you have dark hair, theres no better cover up for thinning than couvre. I couldn't live without the stuff. I dye my hair from blonde to ash borwn just so I can use the stuff to its fullest.
