| Synopsis
| This function converts a 3 value RGB vector into
a color name.
The vector contains the values for red, green and blue in a scale
of 0 to 1.
Black is [0,0,0] and white is [1,1,1].
The matching is approximate and the result is the one which is
closest in euclidean distance to one in the table.
About 650 colours are known to this function.
The full list can be found at lib/Color. |
