Projection system settings are very important. A correctly set up projection system will eliminate the risk of color problems. You should always check the system settings before using it. Incorrectly set up of projection systems may cause color problems. The most common problems are purple or pink-tinted screens and the washing of one color. If the color settings are correct, the problem may lie with the lamp. If the lamp is fine, the problem might be with the cables. The cables may be damaged. The color wheel problem occurs when the color wheel of the projector does not turn correctly. So you can check these one by one and see if it works with the correct colors.
