Their eye colour is usually influenced by their coat patterns and dilutes, however it is possible there is a gene for eye colour that has not yet been isolated. If there is a specific gene for blue eyes, there is a good chance it is physically near a pinto patterning gene and the mutation for blue eyes occurred in a pinto so now that mutation is often inherited together with the pinto pattern because of their close proximity on the chromosome.
I have no idea where you got your information, but it could hardly be more incorrect.
Tobiano definitely does not cause blue eyes. We know that splash and frame do. It is not believed that sabino1 does, but it is the only mutation of sabino that is isolated currently, so it is uncertain if other mutations can cause blue eyes.
Cream also causes blue eyes when homozygous. Perlino, cremello, and smoky cream will always have blue eyes.
