Essentially all of them. The idea that dogs are colourblind is a major misconception. However, their colour vision is less developed than humans.
Dogs are dichromats, meaning their eyes possess two types of cone cells (colour receptors). Humans are trichromats, meaning that our eyes possess three types of cone cells.
Dogs indeed can see colour. However, the spectrum of colour they can see differs from how we see it. When we see the rainbow, we can see the colours red, orange, yellow, green, blue, indigo and violet. A study by Jay Neitz at the University of California Santa Barbara demonstrated that dogs see the world in yellow, blue and grey, with varying shades.
