I guess it depends on what reseachers you read.
I have read a few sites that dogs can distinguish yellow from blue, but not red from green. They see yellow and blue to some degree. I read taht years ago and buy more yellow and blue toys for them when I can.

They have two receptor molecules in their eyes (humans have 3) to tell greenish blue from yellow.
They do have better night vision and great sensitivity to movement.
