Currently, the Color Map feature for devices such as Philips Hue lighting is very basic, meaning it is very limited. It’s really difficult to pick an exact color, or an exact shade of color, as the ability to do so simply isn’t there.
It would be amazing if we could have a full color wheel available to us when selecting which color we would like our lights to be, as it would allow us to really pinpoint the color we are looking for. I am currently attempting to make my lights a warm white, but they always end up looking an ugly yellow, so a color wheel would be awesome, as it would help rectify this issue.
As a side note, if the bulbs support Color Temperature directly, why not use the setColorTemperature() command instead? You could specify the exact color temperature in Kelvin.
