The effect that colours have on eachother in terms of visual presence is bought on by two factors, the darkness of the colour and the warmth of it, these two factors are interchangable depending on the dominant space another colour has around it..... One has to realize that like a whisper gets our attention far better than a loud mouth, the same applies to colour. Naturally a warm hue gets the most attention than a cold one, but our eyes and attention will naturally go to the small speck of colour, the dominant coluor never has any significance except to bring it to the one it dominates.

WITH SECONDARY COLOURS: The colour will look cold when dominated by the warmer hue, but warm when the colder hue dominates, by saying it looks colder it will look in all aspects weaker, saturated and darker if dominated by the warmer hue. The reverse happens when dominated by the colder, in that it will look more saturated, if it's a warm color then it will look warmer when dominated by the cold.
THIS FUNCTION CAN SERVE TO: cause a further sense of depth, when painting an area that is suppost to have depth and shadow you can make sure that it is dominated by the warmer tone around it. the sam can also be applied when you want to depict the foreground, make sure it is dominated by the colder tone if you want to make the warm colour look warmer.

WITH SHADES AND TINTS: be it a tint or shade, it will loose its colour when next to the saturated hues, when a tint is dominated by a dark colour it will look like pure white, but if dominated by pure white it will show its true colour by contrast, the same applies to dark colors being dominated by the tints, they will look darker but more colurful when dominated by that which is darker.

Remember that when colours are dominated by a similar harmonious type it only serves the effect to be easy on the eyes and look smooth, there is no attention drawn, and to the colour blind they may as well be the same colour especially more so if they dont vary in brightness from eachother.
