changing colour of buds food colouring

hi fellow riu'ers sorry if this question has been asked but when we was in school we use use food colouring to change the colour of a plants petals worked best on white petals ie daffodils was wondering if the same princiable would work on bud like as soon as they started to gain root mass every watering give blue,pink,red etc etc food colouring to change appearance/colouring of buds sorry if this q's has been asked an answered peace

i am wondering why you would want to do this besides just changing the appearance?

its plausable for some bag appeal
but most likely the fucked up chemicals in the dye would fuck with your plant, grow a purple strain or somthing if your looking for sum colorful weed

it started when looking on google pictures an we found this picture of a bright pink coloured bud i mean it was bright pink it was just out of curiosoty to tell the truth an was just wondering if you could change there appearance as as soon as we see it i wanted to buy some seeds but the only thing that looks close enough or resembles a slight appearance of it was the auto blueberry but not as pink i know if you make it cool enough some strains will turn purple so yeah really it so just for fun an kicks really you know whem ya m8's come over you bring out a plate of some red buds blue buds purple buds etc thought it would be quite cool or am i just too wrecked

You can use natural colourants too.

Beet juice, for example, is intensely RED and has no artificial additives to it. But as mentioned previously... What on earth would you want to do this for??
