How can I test if I am color blind?

[Eagle Pass]

My father is color blind, and I doubt if I am color blind too. Is there any color blindness test?

The most common test is the Ishihara test. The optician will show you a number of plates which are printed with dots of different colours and ask you to identify the figures (for example a number) among a background of dots in another colour. If you are color blind, you will be unable to identify the figures hidden in the background of dots.
