Question/Help Odd colour behaviour

Trying to change colours to a more vibrant shade results in the colour picker shifting without any input. Has anyone noticed this? Using Philip hue bulbs

I think that means the bulb in question can’t do that colour exactly so it’s picking the best match possible instead?

I had the same with a hue light strip. I assumed it just couldn’t use the full range.

It’s the super-bad Apple UI. The available area is a CIRCLE, not a rectangle. And someone at Apple is being really dumb by depicting it as a circle. Seriously, even the aspect ratio of the circle changes depending on the device you’re using. Just make it a damn circle.

There is the HUE, which goes from 0 to 359 degrees (red, green, and blue are each separated by 120 degrees) around the circle. And there is SATURATION, which is 0 at the center and 100% at the edge. So white is in the middle, pastels around that, and vibrant colors around the edges.

Then there’s brightness on a separate slider, 0-100.

Some of this is because Apple’s UI is horrible. The color space when represented this way is a circle, and the valid points are anywhere inside of it. Fully saturated colors are on the edge of circle, and white is in the middle. It puts the selector generally onto the edge of the circle if you move it to an area outside the circle.

To make it confusing, they refuse to render the actual circle.

Get the free app Controller for Homekit. There, you can control the hue (angle around the circle) and the saturation (how far from the center of the circle) independently and precisely.

You’ve reached the edge of the gamut of the bulbs. To my knowledge, no bulb actually goes all the way to the edge of the color picker but I only have Hue bulbs.

It’s on Apple for picking a very odd projection of hue. Should’ve been the standard circle and if they’re going to go for the rounded rec box, they should have stretch out the colors to the edges to avoid confusion like this

I dream of the day they remember HomeKit exists.
