I would have so they associate the colors with things they can touch, taste, smell, hear... all the other senses they have. Example...
Blue... ice
White... cotton
Pink... sticky cotton candy
Red... rose... soft petals... pricking thorns
Green... freshly cut grass
Yellow... the warmth of the hot sun
These are there codes to imagine the colors, There is not point in aruguing. the color what see may not be a red too. Because someone has named we have been practicing it by from childhood this red, yellow and soo on. like that they imagine and fix the colors of their own....
