There's only so much we can control as artists and this would be one of those things: not everyone perceives colour the same way. This means that people will see your artwork differently to each other and to you. I stumbled upon this cool little colour test on the internet where you can test your ability to differentiate between colours. It was fun and I was convinced I was going to get a perfect score ( but didn't). Here's the link so you can test it out yourself and see where your colour perception levels are: http://www.xrite.com/custom_page.aspx?pageid=77&lang=en
"It is generally believed that around 1 out of 255 women and 1 out of 12 men may have some degree of color blindness. When you consider the importance color plays in the products we buy, our aesthetic tastes, and the design decisions we make when we decorate, it's quite intriguing to consider that many of us may not perceive colors in the same way." - http://www.apartmenttherapy.com
But don't get disheartened if you try the test out and score less than average, afterall Monet's famous waterlilly paintings were created while he had cataracts. This was a condition which effected his perception and ability to produce details and his may have also affected his choice of colour.
