Looks like one of the Gradient Preset: (Basics, Black, White [0,0,0 to 255,255,255]) is wonky when used as is. The grayscale ramp turns green when set to Perceptual Interpolation. However, the same present works correctly when using Linear and Classic interpolation. If I remake or simply edit the gradient, it works as expected. It's not my preferences, and color setting or at their defaults and I'm getting the same error on my laptop with a fresh install. I also noticed when I tried to edit the endpoint it came up specifying "Web Safe" colors which might explain the issue. But the simple act of editing it triggered it to work correctly and setting it back to "Web Safe" didn't recreate the error. Weird!


Anyone else see or able to reproduce this issue?

 

I'm using the latest Photoshop update on Windows 10 and Windows 11 on the laptop.

I'm seeing the same thing.  Black-to-white "Perceptual" gradients have a greenish color cast compared to gradients made with the "Classic" gradient setting.  This is even more obvious if you use Filter > Blur > Average on the gradient and then invert it and keep going back and forth between inverted and not-inverted.   The "Perceptual" gradient alternates between a gray-green and redish-green color while the "Classic" gradient is a middle gray that barely changes when inverted.

No update?  No fix?  This is just terrible.  Thought I was losing my mind with bad GPU or something, turns out it's another new, um, Adobe "feature."

I'm not seeing the change with 23.4.0.  These gradients were made with the Gradient tool on a 16-bit image with Adobe RGB as the color working space.  There's still an off-green cast to Percpetual gradient compared to the completely neutral Classic gradient.
