Colour blindness is a X-linked disease. So, woman whose father was colourblind will be carrier for the disease. So, possibility of a colourblind daughter (i.e., XcXc in F1 generation is 0%.)

Blind has a 50% chance of inheriting the colour blindness gene. If he inherits the gene, he will also be colour blind. However, if he does not inherit the gene, he will have normal colour vision. So, if the man's father was colour blind, it does not necessarily mean that the man will also be colour blind, but there is a chance.

Blind has a 50% chance of carrying the gene for colour blindness. However, if he does carry the gene, it does not necessarily mean that his children will be colour blind. The chance of passing on the gene to his children depends on whether his partner also carries the gene.
If his partner does not carry the gene, his children will not be colour blind but they will still have a 50% chance of carrying the gene.
If his partner does carry the gene, there is a 50% chance that each child will inherit the gene and be colour blind.
It's important to note that colour blindness is more common in men than women, as the gene for colour blindness is located on the X chromosome. Men only have one X chromosome, while women have two. This means that if a woman carries the gene for colour blindness on one X chromosome, the other X chromosome may provide enough normal colour vision to compensate. However, if a man inherits the gene on his X chromosome, he will not have another X chromosome to compensate for the colour blindness.
If his partner does not carry the gene, his children will not be colour blind but they will still have a 50% chance of carrying the gene.
