Wrong color when picking from left bottom about react-native-color-wheel

[jsdario]

I'd really appreciate if you could attach a screenshot with some log, so I can appreciate which is your exact case.

We are using https://github.com/netbeast/colorsys to convert colors back and forward.

Highly saturated colors (whites) can be translated to red in some scenarios, since they lose their color information in (white in rgb is {255,255,255} but in hsv, hue is an independent variable, so its info is kept safe).

Don't know if that's the case of tinycolor, in colorsys there it is a test implementation:

Thanks for your quick reply @jsdario

Actually I just found the reason and fixed it like this:

When dragging in that area, for instance at 7 o'clock blue color, picker returns a value like so:

{ h: -134.48844413341297, s: 87.99901795187165, v: 100 }

The correct range for h is [0, 360], so obviously tinycolor converting to hex will return some other colors like red (I was just logging the final result at the beginning).

All I did is a small check:

selected(color) {
  if (color.h < 0) {
    color.h = Number(color.h) + 360;
  }
  // do whatever I want with color
}

That's it. Hopefully it would be helpful for anyone else who is using this component.

Oh I see! Since I am collaborator here and in colorsys I considered hue as any possible valid angle in degrees.

Thanks a lot for your contribution! Will close the issue with a solved tag :)
