Colour replacement tool not changing colour.
I am trying to change the colour on part of a photo in CS6. I am using the Colour Replacement tool. I want to change a black item on the photo to a lighter colour from another part of the photo. I used the Eye Dropper tool to sample the colour I want to use, swap to the Colour Replacement Tool and paint over the area. The colour changes to a rusty brown colour, whereas I have samples from a champagne colour. If I sample from a colour such as orange, then the colour brush will change the area to orange. I am working on a jpeg photo, in 8 bit mode, if that helps.
On the photo, the brown part at the top of the pannier was sampled from the petrol tank and the lower orange shade was sampled from the indicator lens.
