A method to adjust the colors of skin of a graphical user interface (GUI) of a customer relationship management (CRM) application based upon a color scheme of an operating system is provided. In the method, a color code of the color scheme of an operating system is fetched from a registry entry of the operating system and is saved as a base color. This color code is converted from ARGB format to RGB format and further converted from RGB format to HSL format. Different luminance values are set for various elements of the CRM application to provide different brightness and legibility to different elements of the GUI. The modified color code is converted back to RGB format and assigned to various pixels of GUI skin whereby the CRM application is rendered with new color scheme similar to that of the operating system.
