Lightroom Classic with random colors

Lightroom Classic can sometimes display random or unexpected colors due to issues like incorrect color profiles, GPU incompatibility, or monitor calibration errors. This can make edited photos look different from the original or vary across devices. For designers, photographers, or anyone doing precise visual work—such as creating consistent backgrounds for product photos—these color shifts can be frustrating. Ensuring your display is properly calibrated, updating Lightroom and GPU drivers, and using the correct color space (like sRGB for web) can help. Accurate color management is essential, especially when working with tools that rely on precise background or object color consistency.

The red aeras in you pictures are over exposed and the clipping warnings are enabled.
