Colour vibrancy can be a strong design tool, because it can play a big role in how the brain analyses certain lighting situations. As long as you apply the basic rules, you can use more stylised colour choices that will help to give your scene a specific tone and feel. You can boost colour vibrancy with an Adjustment layer. In this painting, if I had to adjust the colour vibrancy that’s created by the sunlight shining through the fabrics, I would create a Hue/Saturation layer, select Reds instead of Master and increase the Saturation level. This approach means I’m only altering the saturation level of my red tones, and not changing other colour channels.
