In the 27.1.0 release, I confirmed that an option has been added to remove the background gradient in the Tone Curve panel. However, the curve line has become noticeably thick. In addition, in the Light UI, the RGB/CMY channel colors appear to have a slight tint, but they are almost indistinguishable. It would be ideal if the UI could be refined using the 2024 version as a reference. Further adjustments are still needed. Please use colors that remain clearly visible across all UI themes.

Please examine the 2024 Tone Curve UI carefully and consider how professionals actually use it.
