I think what you are seeing is the highlight clipping warning. Click the box above the right end of the histogram and the red will go away.

Not on my system using Bridge and ACR.

In photoshop select 'New', then 'custom 3600x2700 300 ppi

eraser - wipe out the white background

Rectangular Marquee tool - select the first color bar

open color picker, select r-255, g -0, b-0 Paint bucket - fill the color (use a brush if it's easier)
repeat: 255,128,0 (orange), 255,255,0 yellow, 255,255,128, 0,255,255 0,128,255
255,0,255 255,255,255 (white) 0,0,0 (black)

save a jpg, tiff - makes no difference

I tried essentially the same procedure on PS, new white canvas, rectangular marquees, fill with RGB colors, saved as Jpeg then opened ACR via filters but I didn't get any color change. I'm on PC. Not sure I did the same process as you.you.

I made a new image.
Produced an empty layer.
Rectangular marquee -- used paint bucket to fill it with red (255,0,0)
Another filled with green
another filled with blue
another filled with cyan
another filled with yellow
another filled with white
another filled with black.

turned off the background layer which was white so some of the areas between the color bands are transparent, but that translates to white in the jpg.

Exported as a psd, tif, jpg, and png. (The white band is surrounded by transparent areas that are white in the jpg so it's not distinct).

Loaded the jpg into PS. Applied the camera raw filter. Nothing changed.

Trying to understand how, using RGB yellow, orange, magenta,black, white and all the shades in between are created. It started out when I found gray = r,128, b,128 g 128.

And what happens if I put an orange layer behind the background and reduce the opacity of the background layer.

try 64,64,64 and 192,192,192 what do you get?

Digital color devices yield a finite number of shades. (Analog is infinite.). The range of colors and the number of shades is called the color space. Real (analog) colors can fall in between those shades or outside the range. That is called out of gamut and there is a lot of math involved in mapping those infinite colors to the finite color space.

Usually it works well but now and then you ten across a color that doesn’t look quite right in the digital mapping.
