Asked in Domestic Dogs, Color Blindness

Are dogs colorblind?

Dogs are not color blind - they see color, but their chromatic acuity is significantly less than humans'. This is for two reasons: (1) dogs have far fewer cone cells in their retina (cone cells are responsible for seeing color); and (2) dogs are dichromatic (they see only two primary colors - blue and yellow) whereas humans are trichromatic, meaning we see three primary colors - red, blue, and yellow. Humans have 7 times higher proportion of cone cells than dogs, meaning that...

Asked in Wild Dogs, Color Blindness

Is there a way to beat the Ishihara test for colorblindness?

Beat it, meaning cheat on it? Sure. Plenty of ways. You could study the test ahead of time so you know by the patterns what number is there; you could have a non-colorblind friend tell you the friendus; you could bribe the doctor... so many ways. My question though is why in the world would you want to? The test isn't for a grade... it is to determine whether you are colorblind, and that is something that it is helpful to...

How can you describe the color pink to a blind person?

You can't describe it. The color pink is strictly visual - it is a light of varying wavelengths and frequencies. Just like you couldn't answer what pink sounds like; the color pink will always remain foreign to a blind person. That is a beautiful question you have. Pink is the soft pillow you felt as a baby or the soothing voice of your mother. You could also describe pink using the sense of taste, such as bubble gum flavored ice cream. I also...

Asked in Pool Heating, Colors, Color Blindness

Is the best color of solar cover black blue silver or clear?

I was told by a pool supply store in Cleveland, Ohio, that they have heard of more instances of the black covers falling apart than the others. The guy in the store suggested it is because the black absorbs more of the sun's heat, causing the more rapid breakdown in the material. He had heard nothing about the clear covers, but speculated that it would hold up better than the black. Swimming pool covers help retain pool heat by reducing evaporation....

Asked in Painting and Staining, Colors, Color Blindness

Why is the color red an appetizing color for people?

The Allure of Red Speaking somewhat physiologically and psychologically, yellow is apparently the most significant colour that makes people want to eat (so a definite bad idea for the kitchen), however probably because we often associate red with feelings and emotions tied in with love, passion etc. Therefore people see it, it's a warm colour, we feel that instant comfort and security etc. Hope that starts you off. Satisfies our primal instincts Not sure if there is any scientific data, but most humans eat meat and red...

Asked in Computer Hardware, Color Blindness

If the color red has totally disappeared from your desktop why has this happened and what if anything needs to be replaced?

My guess is the video card is going bad. Try replacing that. If you have a spare monitor you may want to try viewing your desktop on a different monitor before going out and buying anything. First thing I would check is the cable between your monitor and computer. Swap it for another cable if you can detach it from the back of the monitor. If not, leave it be. The inside of a CRT monitor is a dangerous place. You...
