Description

One use for the color difference formulas is to find the closest color from a set to a given color. A good data structure for this seems to be a v-p tree (Vantage Point Tree), as it allows for much faster queries than the linear approach.

Contributor guide

Research direction
Study the v p tree algorithm and implement a nearest color search function that uses existing color difference formulas.
