The light was catching the bottom of the lapel and press stud so this area will be made lighter. The sun tends to 'bleach out' colour, so one of the ways I try to depict this is to make the colours much lighter and add areas of white to provide the largest contrast. There is still a hint of the cerulean blue to add in patches on the edge of the lapel but I wanted to get the first colour to the bottom of the jacket.
There will be a little if the blue and red on the left hand side which will balance the colour on the right.
