Hello @youxue ,

To me it doesn't look like a "TouchGFX" issue but more a display (configuration?) issue. What display do you use? Do you have backlight ON? Could you check your display driver and adjust gamma settings?

[youxue]

backlight  is on.i use stm32cubemx  Generated project. All other colors are quite normal, but it turns out that purple doesn't work.

Often, it is not only one color but all colors that are affected by the issue. However, sometimes the effects are less perceptible. Applying an extra layer, such as a box widget in the foreground with a specific color and alpha value, can also be an easy workaround. This approach slightly modifies the color to match your expectations, but it will still not provide the same visual appearance as on the simulator.
