I'm starting to suspect there might be a mechanical rather than chemical cause at play here.

I just turned on the enlarger, set 105M / 95Y and the light is bright red. When I swing the red filter under the lens, I cannot tell the difference.

If I dial 60M / 50Y, the image looks more like what I'm used to seeing when I print.

The back of the Kodak paper box, incidentally, recommends a starting filtration of 65M 55Y.

Too late in the day to experiment now, I'll report back tomorrow after changing the developer.
