+Color scheme can be set using a predefined color scheme or a custom one:
+1. To use a predefined color scheme, the name of the scheme must be provided. Possible values are:
+* "nvidia":  Use NVIDIA default color scheme
+2. To use a custom color scheme, 4 colors must be given in RGB with the format: R,G,B:R,G,B:...
+The first 2 colors are the GPU art color and the following 2 colors are the text colors

+Peak performance information is NOT accurate. gpufetch computes peak performance using the max
+frequency. However, to properly compute peak performance, you need to know the frequency of the
+GPU running real code.
