Can't select black with rgbPicker

Troubleshooting
1

Here’s my minimalist test case. I couldn’t get the picker to set this to black (0,0,0) no matter
what I tried. White (1,1,1) works fine – upper left corner of any color. Am I missing something obvious?

This was running on a Pixelblaze 2, with v2.28 firmware. It behaves the same way on a Pixelblaze 3 with the latest firmware though.

export var r1 = 0.1;
export var g1 = 0.1;
export var b1 = 0.1;

export function rgbPickerRGB(r,g,b) {
  r1 = r; g1 = g; b1 = b;
}

export function render(index) {
  rgb(r1,g1,b1);
}

Same here.

Looks like the Picker only reaches zero in two corners, and then only for the blue component. Sliders work as expected.

While building a test fixture, I also found that the editor mistakenly interprets variables that start with slider as UI sliders.

Looks like an update to the color picker library fixes things. I’ll include that in the next update. Thanks for the report!

@pixie , yes, controls work by invoking a sequence of magic words (export + one of the UI control words at the start). :mage: Invoking these magic words together with variables that aren’t intended to be UI controls may product harmless, if unexpected, results.
