One of the problems of designers nationwide is color. Color combinations, color schemes, color shades etc. all pose a problem to designers. A lot of my colleagues complain a lot about this problem. I was once stuck on a project for months just because of color variations.
My advice to designers and color users out there is to take time out to study colors. At first sight, this would seem irrelevant but it is a very important aspect of designing. A good logo, good website, good flyer, whatever it is, requires a good eye for colors. In fact, good color combination is what set good designers apart. So take time to study colors and enjoy designing.
