Colours have a powerful effect on us. We can use this to calm and relax ourselves. The colours we need to know are the colours of the rainbow.
ROY G BIV is a common mnemonic to remember the colours of the rainbow:
Close your eyes. Visualise red( u can fill the screen with red, or think of a red object). Then go on to orange, yellow, green, blue, indigo, and violet. See how you feel. Are u becoming more relaxed and calm?
If you find it useful, use it. Being able to be calm and relaxed is an essential part of living well.
