"Colour Blindness"

I just had a phone call from a colleague asking about how to connect the plugs from the case to the motherboard, such as the LEDs and power, etc.

I proceeded to get a manual and told him which colour bits to put the plugs on. Sounds simple enough... rite? No he's blinking colour blind isn't he.

He is filling in for someone who has gone to cyprus for a few weeks, and is usually involved with the software set-up, so a bit of a newb.

I took about 40 mins trying to explain which pins to use with each plug... *bangs head*. Such a simple task... but noo..

Just out of interest and the whole point of this post. Can someone explain colour blindness to me :p?

that's why u get decent pool balls that are dots or stripes init.

One of my mates is color blind.

He has difficulty when we play Pool....

They're lying to you - don't believe a word of it. Actual colour blindness is where you see white people as black people and vice versa.

Thanks. One of life's great mysteries solved. I should have thought to look in my A Level biology books :p.

Thanks, BBC.

To see colours properly, colour detecting vision cells, called cones, are needed in the retina of the eye. Three types of cone cell exist, each being sensitive to red, blue, or green light. If one or more of these types of cells is faulty then colour blindness results.

Colour blindness is hereditary and is usually due to an abnormal gene inherited from the mother. Genetic colour blindness only affects men.

Sometimes colour blindness occurs because of diseases such as macular degeneration or from side effects of medicines.

What causes it? What's the problem with their eyes?

It depends what kind of colour blindness...

And you don't see different colours at all. All it is is, is (is) that you have difficulty distinguishing between two colour when they're close.

Like red and green. If there's green on a bit of paper, and its shade changes to merge with red, it's hard to tell where they change and stuff.
Yus.

You see a different shade of the colour than other people, or an entirely different colour. Also, two shades of the same colour may look identical to you.

Err... same thing but with different colours isn't it obvious?
