603010 Inspire Me : 603010 What is 603010? 603010 is a colour selection tool that assists you in making colour choices, and helps you to use colours in the right combination and schemes that complement one another and the environment that is being painted. 603010 is based on the principle that the main colour in a room should take up 60% of the available surface space, while a supporting colour takes up 30%. The remaining 10% should be an accent colour for feature walls, furnishings, accessories, etc. The 10% colour can be Monochromatic colour (a diffirent shade of the same colour hue).   Complementary (colours on the opposite side of the colour wheel), or Adjacent (colours on either side of the colour hue on the colour wheel). Using the 60-30-10 principle in decorating your room will help you to create the ambience that you are looking for. The section allows you to try out some pre-selected 60-30-10 schemes in various rooms.
