Solomonoff induction involves defining complexity. Green and blue aren’t the most basic possible things, so you can’t straight up stick in grue and bleen, but you still can come up with some language where grue and bleen are just as easy to define as blue and green are in whatever we’d be likely to use. All Solomonoff induction can really do is specify that the probabilities must add up to 100%.
