is there such thing as a black flower?

Question

the true color black.

Answer 1

There are naturally occurring flowers that come very close like Lisianthus nigrescens with large purplish-black flowers.
A flower looks black because pigments in the petals absorb red, green, yellow and blue light. With all the light being absorbed none is reflected back off the petals so they appear black.
Carotenoids are pigments that give red, orange and yellow colouration, while anthocyanins are responsible for blue, red and purple colours. Pigments need sunlight and most black plants being highly pigmented grow best in direct sunlight. However all show hints of color, none are true black.

Answer 2
