I am going to photograph my subject on a white background and add the colour in afterwards. This will allow me to make any colour background I choose and enable me to select the best colour background for the image, It will also make the portraits more efficient because I won’t have to buy and carry lots of different coloured backgrounds.
Choose the colour that you want.
Take the opacity down to around 30% and change the blending mode to multiply this shows a little bit more of the subject but it is still a little yellow on the bird. paint in a layer mask so that the background is the only part effected by the colour.
