I have some E14 bulbs from NEO connected with my Hue Bridge.
When I used them with Essentials for the first time, I appeared that they have a horrible color accuracy.
However, I just tried Huetro for Windows as another app to control Hue. With Huetro it was suddenly possible to set the colors for these same bulbs very nicely. For example I could set a perfect orange, which I could not set with Essentials, even if I entered the Hex-Code #FF6200 manually.
So it must be something wrong with the way how Essentials handles colors in some circumstances.
That would be so perfect, if this could be fixed.
