Agapanthus colour is normally genetically determined, as such a white flower cannot turn blue. This does happen with flowers such as Hydrangea, where a blue or white flower can be turned pink - this is a result of the pH or acidity level of the soil

The acidity or alkalinity of the soil can change colors of flowers. You will need to get a Ph kit and adjust this to the color you desire.

Florists sometimes put white carnations into blue dye. The flowers absorb the dye and it turns the flowers blue.

African blue lily, bigleaf hydrangea, blue Egyptian water lily, blue lupin, blue-eyed iris, chicory, cornflower, mealycup sage and small globe thistle are examples of blue-flowering plants. Specifically, the African blue lily (Agapanthus praecox) flowers dark blue. Bigleaf hydrangea (H. macrophylla) has blue or pink flowers respectively depending upon whether the soil pH is more (5.2-5.5) or less (6.0-6.2) acidic. Blue Egyptian water lily (Nymphaea caerulea) offers pale bluish white to mauve or sky blue flowers which open between about 9:00 a.m. and 3:00 p.m. daily. Blue lupin (Lupinus angustifolius) has bluish to pinkish to violet blue flowers. Bue-eyed iris (Aristea ecklonii) offers cheery blue flowers which open only in bright light and which will last only one day. Chicory (Cichorium intybus) produces bright blue flowers even though occasionally it will flower pink or white. Cornflower (Centaurea cyanus) offers intense blue flowers. Mealycup sage (Salvia farinacea) produces navy blue flowers. Small globe thistle (Echinops ritro) sports flowers which develop from silvery blue into bright blue.
