PHOTOSHOP ELEMENTS 10 DEFAULT COLOR SWATCH ERRORS
Swatches for the range of grays from white to black have incorrectly named %ages.
For example '50% GRAY' is NOT 50% but is about 42% (R.147 G.147 B.147).
There is NO 50% gray swatch (R.128 G.128 B.128) in the Default set!
Grays need to be renamed and 50% Grey needs to be added to Default Color Swatches.

The gray swatches are in grayscale space - so related to your grayscale profile, not your RGB profile. Because the profiles have different transfer curves, the values won't seem right in RGB.

Also, 50% gray is not RGB 128,128,128 in most colorspaces.

Dear Chris,
Many thanks for your speedy reply.

Sorry I don't really understand the explanation, much too technical for poor old me. I just assumed that 50% of 256 is always 128. I'm a very elderly PSE beginner.

I was trying out a method of Burning & Dodging using a layer created from the Menu>New Layer, in Overlay Blend Mode, filled with Overlay Neutral Color (50% gray), which actually produces a gray fill R.128 G.128 B.128.

Painting on this layer with lighter shades of grey dodges, while darker burns.
Overpainting with the same gray as the fill gray effectively erases any burning and dodging.
However, erasing was not possible using the 50% gray color swatch because it is R.147 G.147 B.147, much lighter than the Overlay Neutral Color 50% gray fill.

I have now created a new color swatch to use for erasing, R.128 G.128 B.128, which matches the Overlay Neutral color 50% gray fill , so I can now erase.

Puzzled as to why Overlay Neutral Color 50% gray is different to the 50% gray color swatch, but guess I can live with that.

You're not working with numbers, you're working with colors.

You have 50% gray, which is associated with your grayscale profile.
That can be converted to 50% gray in your RGB profile, but the numbers will differ depending on the profiles.

If you need exact numbers (instead of exact colors), create a swatch in the same color model that you'll be painting, with the numbers you need.

Dear Chris,
Thank you again.
I have now changed PSE's Optimize Color Settings from 'for Printing' to 'for Computer Screens'.
Now the Default 50% Gray appears as R 129 G 129 B 129, which is as close as possible to the Overlay Blend Mode fill with Overlay Neutral Color (50% gray) R.128 G.128 B.128.
So, now I can ERASE dodging & blending in the Overlay Mode Layer, simply by using the Default 50% Grey color swatch, and all grey-color swatch percentages reflect the uses of grays for Dodging (%ages below 50%) and Burning (%ages above 50%).
Problem solved, thanks.
