    I am partially color blind. Some shades of green I will mis-identify as blue (if it is more on the blue side) or tan or brown (if it is more on the yellow side). Grass green is no problem and fire engine red is not a problem. Purple is usually a problem for me, I will see it as blue most of the time. Primary colors are usually not a problem for me. The question is this, will I be able to use the Avia DVD to calibrate my set with my handicap?

    Greetings

    In most cases, you should still be able to correct things until they match your own perception of what "correct" is.

    Much of the work is light intensity based , not colour based.

    To expand on what Michael TLV said, color calibrations are done by looking through colored filters. Ironically, when you adjust the color and tint controls, you can't see the actual color and tint you're adjusting. Through the filter, you make adjustments until certain areas on the screen are of equal intensity - NOT of equal color.

    You shouldn't have any problem.

    Jim,
    Sounds like you and I have the exact same color deficiency. As Scott said, color adjustments using Avia involve matching colored areas, not adjusting anything to a specific color. I have used Avia to calibrate all of our TVs including our 42" plasma and my wife (her color vision is perfect) thinks everything looks great.

    Good luck,
    Steve

    I've used Video Essentials to do this, and haven't had a problem. Convergence adjustment on the other hand is a bitch...

    Jim, I have the same issue as you and Steve, and have to agree with Steve. It's a moot point if you're using a calibration disc and filter. As a matter of fact, most men, whether they realize it or not, have this same color blindness, but to varying degrees.

    I can tell primaries, but close shades throw me for a loop. I get lost on a beige, peach and pink if they are all the same intensity. Same with a dark purple, black and dark blue.
