Setup for Ray Wu Rectangles

[IndianaChristmas]

I am using the Rectangles (1804) that have been listed on the DLA boards from Ray Ru.
For the life of me I can't figure out what RGB combination these are.  I have tried all the different setup options in XL4 and the colors still don't come out correct.
What is the RGB combination for the rectangles?

You need to run the test sequences from the controller first to deduce that rather than from XLights.

The ones I got 2 - 3 years ago were GRB but may have changed. Easy to test with XL/NC. Go to Test panel, clear all channels, In RGB mode, select Background function and set all background colors sliders to 255. Then select the first channel of the first rectangle. Whatever color you get is the first value, unselect that channel and select the next to figure out the next value, and repeat with the third. That's it.
