I have recently posted some images of hares and Steve suggested I check out the colours, I noticed his repost was an improvement and then I did further reposts. This reminded me that I frequently forget to check the colour balance temp or hue, especially when I get an image that I have been trying to capture, I am usually in too much of a rush to post!
Here is the link and also the link shows a reference to a site where you can check out your own colour vision, I do need to stress that if your screen is not correctly calibrated you will not get a reliable result.
