Display color calibration

Thank you for your reply. I've tried that several times now.

I got to the Display Calibrator Assistant, and left native white point as is, first, and continued through to the Conclusion. I saw no way to make any adjustments or choices at this point, and clicked the Done button, to return to the Select a target white point to unclick the Native white point.

I moved the slider from all the way left, to all the way right to adjust the white point. Although there is a distinct color temperature adjustment, there is no correction of the red-to-magenta shift. The colors across the spectrum do change somewhat. But there is no actual red, only a bit brighter magenta, and not nearly enough of an adjustment to be useful.

Which leads to the question: what reason could there be for the display to produce false color without me having done anything, other than change the outline color of the cursor, to magenta--other than Ventura, I have made no upgrades.

Yes, Kurt, it's clear now that, inadvertently, I had activated Color Filters when I was changing the color of the mouse pointer from white to magenta. I didn't know there were color filters to correct for eyesight conditions, that might also affect color calibration across the board. Even though it is logical.

There's something ironic about going to Accessibility to adjust only the color of the mouse pointer outline, and notice later on that colors were adjusted globally, from there, and then going to the Displays section but find nothing there to fix it, but something else.

It's very interesting, and useful to see all the other wondrous things to be done in the Accessibility section. I'll make a suggestion: to include Accessibility-Display in a search for "display color calibration" along with Display.

Thanks very much for sharing your knowledge, Kurt. I've got all the bright red I need!

Thanks for your assistance. I'm over my head in the topic of calibration, and so I assume that they are the equivalent on the 2010 as the 2020 machines. The operating systems have changed a lot meanwhile, however.

I'm running Ventura, which has revamped System Settings (for the better). On the older machine, it's High Sierra, and the color settings routines look, well, gnarly to me by comparison.

Thanks again!
