Colour selector does not move

[Ba11istix]

Wheel isn't big enough to show all colours, when you click a colour the wheel tries to select it for you, in some cases it cannot do this as the resolution is not high enough.

Solution 1: Change the search from pixel by pixel to moving the selector to a calculated point.
Solution 2: Move to a colour that is close to what we want.

Potentially also rounding issue, needs further investigation.

this is resolved by this pull request #3. RGB and hexadecimal codes has been added as selectors resulting in better movement of the selector wheel and slider
