UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
@vincent-mod
thank you, yes that worked with the luminance channel at 5% - very helpful, thank you.
@imnewhere This is EXACTLY my same problem.  Instead treating L as the intensity and RGB as the colors to paint it, when I do it, it treats L like a white layer and the picture is always just white even though all L, R, G, B, is there,... what's going on with this??

Hi Skye @skysong,
When you apply a luminance layer 100% it can seam that the image is whitened. But if you simply enable saturation and/or increase saturation in the preview filter, the colors will be there. Our RGB combine tool works currently with the HSL color model and L is a real L, not a white layer.
I have opened a new issue on my todo list to have a good look at the Luminance calculations to make the RGB composites in the RGB Combine Tool.
I know that this whitening effect is there, so I will definitely try to have this work better going forward 😉
It is on our todo list, to improve this with a more advanced color model going forward.
Please let me know if this helps,
Mabula
@mabula-admin Thx. So in a true Luminance situation, increasing L slider would increase the colors, but in our case, in just increases White, so something needs to be adjusted to look to RGB instead and proportionately apply the "L" to boost that but not as a layer just as factor to see how much to increase the particular color, as above, for example New G = L * (G / (R+ G + B), where L itself is not displayed as a "color".
On the left is APP's RGB combine tool on LRGB, and on right is taking the L and RGB to Gimp (same data) and using the "layers" to associate the L with RGB so it stacks the intensity of the L as true Luminosity, not a white layer, as described above. This is how APP should be doing it (without having to go to another tool).Â
