For the blue offspring example, you would "expect" to observe ~25% of the offspring to be blue (1/4 of the punnett square would be homozygous recessive bb) the other 75% is a mix of genotypes (50% heterozygous and 25% homozygous dominant), but will still give you the normal phenotype. To avoid confusion, I would probably put pictures of the parent being plain-colored, and the offspring blue (the way you have the pictures and wording presently implies that heterozygosity gives you the desired phenotype).

This is a great little "crash course" in Mendelian Genetics, though!
