I can't see any numbers in these tests.
That's funny, because two of them are designed to be visible regardless of color vision.
This color-blind label does not mean we cannot tell the different between the two colors in real life.
There are actually four types of red-green color blindness, varying from missing either the red or green receptors to having mutated spectral response curves for either er dor green. According to Wikipedia, the most common type of color blindness (6% of the males) is one with a mutated green receptor, where there is only a problem in distinguishing subtle hue differences in red-yellow-green colors. Since you are able to read resistor color codes, you probably have this. Your personal observations are not necessarily representative of what people with other types of color blindness see. For example, I know people who can hardly see the red dot of a laser pointer (during a beamer presentation) due to a missing receptor for red.
