Color balance gets better now, although still a little bit greenish than preview JPEG and DNG.

@ktgw0316
EDIT: I was able to convert your 2 examples to JPG and try them in LZ. NOTE: I tried the Channel Mixer tool but was unsuccessful in getting color balance. I tried the Color Balance tool without perfect success as well. I had good success using the Hue/Saturation tool. I agree that your fix of using camera_matrix is a little better. Are there any other options available? I can't see how to add the images to this post. @ktgw0316 UPDATE 09/11/23 - I found perhaps a better method of using the Zonemapper tool, selecting the zone to modify (lighten), and finally changing to the "RGB" instead of the default "Luminosity" button. I don't know if any of this helps or not. The HSL tool may be better though.

@ktgw0316 This is not fixed, see attached. It worked on the one R5 CR3 image that you provided from the website, but not my image from my R7 camera. I thought that the R7 camera was included in the Libraw list of cameras, see Libraw camera list HERE.
