color crossfade and black out issues, Source 4 lustr S2

The first is because you've patched them in a one of the HSI - Hue Saturation Intensity - modes.
The HSIC mode is designed for television and film, where accurate color and color temperature matching are extremely important but fades between colours are less so.

"Hue" is the position around the colour wheel, where 0% = Red, 33% is Green, 66% is Blue and 100% is back to Red.
Fading Hue goes around the colour circle - so a fade from Red to Cyan goes through Green

Saturation is the distance from the nominal "White" point at the centre of the colour wheel, so a fade from 0% to 100% goes from "White" to "Deeply Coloured".

Thus a Hue-Saturation fade may give surprising results.

Second:
A Source Four LED fixture has several different dimming curve options that affect the curve and rate of the fade.
Try some of the other options.

Thank you.
I have not been attentive enough and read only about a third of the manual.

Hello.

I have some similar problems with lee 201.
It gives a green color.

I have patched me lustr2 in quick setup - stage.

Hi Jon. Do you mean the cross fade is a bit green or when you bring up the color you think it's a little to green? You can always easily adjust a color to your liking using the Tint function in the color picker. Click the gear icon or in 2.4 click the tab and turn on the Tint option.

The color lee 201 looks realy green.

In the warm colors they look correct.

I work on a gm2.

This is a problem with the way that the GrandMA 2 handles color on the Source 4 LED fixtures. On an Eos console, the color match to L201 on a Source 4 LED is as close as I have ever seen on an LED fixture. You should post on the MA lighting forums and see if anyone has a better fixture profile, or if MA can update theirs.

Alternatively, you can mix a color that matches L201 better to your eye, and store it as a preset.
