Interface Detailed Explanation:

Rows 0–15 in Column 0 are non-pressable and for display only. They correspond to the color and brightness of Levels 1–16 on the Grid respectively.

Note: The displayed brightness may differ slightly from actual brightness, as these colors are affected by the red LED brightness in Column 1.

Rows 0–15 in Column 7 are pressable and used to select color presets. From Row 0 to Row 15, the presets are cool white, orange, red, and so on. You may switch between several to observe the color changes in Column 0.

Columns 1–6 are for fine-tuning colors, supporting both short and long presses.

Columns 1 to 6 correspond to Strong Red, Weak Red, Strong Green, Weak Green, Strong Blue, Weak Blue.

Pressing them increases or decreases the corresponding RGB value for the same row in Column 0.

Example:

To increase the R value for Column 0, Row 3 (Level 4), short or long press Column 1, Row 3.
To decrease the B value for Column 0, Row 7 (Level 8), short or long press Column 6, Row 7.

Once adjusted, the color settings are automatically saved to the corresponding preset and will persist after power cycling.
