I tried it. Here's my first result:

Hi Scott, Ted,Interesting. Thanks Ted.Hmm ... ??Hey Ted, if I set the upper warning level to 255 instead of 254 the warnings are not so "strong" in SPP. I guess I could have reduced Exposure a bit, to get that histogram to move left a little, but I figured it wasn't necessary, because over-saturation is o.k.Didn't look today but did you notice the blown red channel in the Standard's histogram and all the red warnings in the review image?Thanks Scott, getting late here so I'll look at it tomorrow.
P.S. just now noticed that the Landscape's reds are also blown but the Neutral's reds are not - meaning that the Neutral conversion is closer to the actual scene than the other two.
P.P.S. more attention should be paid to the SPP histogram before exporting the review image.
P.P.P.S. in a review image with a blown channel, in this case red, the color balance is already off and reducing the Saturation slider does not fix that even though it appears to, sad to say.
Voila, your Standard post, one GIMP adjustment:
Arrow points to selection I used for the adjustment.
Area selected for the Color Mixer:
After adjusting the mixer:
Observe the RGB histogram - lining up the red and green peaks gives the yellow you are apparently looking for.
There's caveats using the mixer which I didn't bother with for this where the only interest is the yellows.
I could have turned the yellow to blue ... have a go ...
EDIT:
I tried it. Here's my first result:
how about a hue adjustment? Here is an adjustment of hue +7. It is available in GIMP under "Colors" > "Hue-Saturation…".
Looks good from here, Paul!Hi Scott, Ted,

I decided to add at least one more sample photo, processed in SPP 6.8.4 (if I remember correctly), and this one includes a yellow tomato:
Tomatoes shot with 50mm f1.4 Art @ f11 on SD Quattro H.
I processed this one with the color mode set to Neutral, using the 16:9 mode for the final image. This is something that is apparently only available in SPP when manipulating raw files from newer Sigma cameras, such as my SD Quattro H. I am assuming the fp and fp L raw files can be used with such modes too (and probably more color modes too).
Settings for above image
Here's another version, using Foveon Classic Yellow color mode, and just 5000K white balance, rather than 6300K:

The photo seems a bit color-tinged. I tried this edit with an adjusted white balance and a hue shift from red to yellow:I decided to add at least one more sample photo, processed in SPP 6.8.4 (if I remember correctly), and this one includes a yellow tomato:

In spite of the hue shift, the tomato appears to have stubbornly remained orange, according to my screen color picker.The photo seems a bit color-tinged.

I'm thinking that the offending tomato was always orange in color, not yellow as initially described ...

Well, as I see it, that "yellow tomato" is sitting right next to an orange tomato (which we often describe as a red tomato, though we all know it's not quite red). It may have an orange tint to it, but it is clearly a yellow tomato as much as any of those tomatoes are "red" tomatoes Ted.In spite of the hue shift, the tomato appears to have stubbornly remained orange, according to my screen color picker.The photo seems a bit color-tinged.

Are you trying to prove to us that a hue of 29 degrees is not almost pure orange ?!!

Thanks for showing me that Ted.The visual aid really helps. Now I'm perplexed as to what "yellow" things out there may actually be orange.

We humans tend to classify stuff like color into rigid subdivisions to keep life simple ... so, the term yellow could indeed include all colors between say 45deg and 75deg hues, and orange could be between say 15deg and 45deg, and so on. By so doing, we would split the hue circle into 360/30 = 12 subdivisions but only have 12 color names ... and 45deg hue is actually either orange or yellow from that point of view.
... not enough for aesthetic types who have found a kajillion names for ever-increasing sub-divisions of color.

This "orange vs yellow" discussion has reminded me of these two videos -
They talk about yellow lasers, and issues associated with pure yellow color.
Also, interesting, how different viewers picked slightly different version of what they see as yellow in the comment section.
