Thanks for sharing this informative and interesting post regarding colours and yes colours have great impact in our mind and i have read somewhere that in rainbows couple of colours are production of our mind means for example if you are watching two colours your mind can possibly create the third one i don't know it's true or not but i have read somewhere. And colours have great impact in our life and some colours give positive essence and some give negative essence. Wishing you an great day and stay blessed. 🙂
