what kind of computer/monitor do you have? i've noticed that some of my pictures will look COMPLETELY different on my mac than my older desktop up at work. you sure it's not just your computer monitor that is a little off color?
as far as cameras go, were you wanting a dslr or just a point and shoot? when i first got my canon t3i, i was blown away by how vibrant and clean the colors were (still am, really). and the display of the camera reflects the actual pictures pretty accurately. definitely captures the true colors of my snakes pretty nicely.
