    Hi everyone, I'm trying to select the color from a point cloud (in the geo context). Separate them to apply a different pscale attribute depending of the color value. With VEX , it's easy to select separte RGB and CMY values with addition and subtraction : Red = @Cd.r - @Cd.b - @Cd.g Green = @Cd.g - @Cd.r - @Cd.b Blue = @Cd.b - @Cd.r - @Cd.g Cyan = @Cd.b*@Cd.g-@Cd.r Yellow = @Cd.r*@Cd.g-@Cd.b Magenta = @Cd.r*@Cd.b-@Cd.g My problem is that i lack a precise value to separate intermediate values, pastel colors, colors between two primary colors, etc ... How can i pick a special color to applied precisely my pscale value. Is it a good way ? Is there an other way to have a color picker ? a Keying function ? Hope this is clear, Regards,
