Colour me purple!

Advatek has released firmware v3.14.0 for its PixLite Mk3 pixel controllers, introducing Color Intensity Scaling, a pixel-tuning feature that provides independent brightness adjustment for individual colour channels. The feature allows brightness scaling at the pixel output level, enabling users to balance white points and improve colour consistency across different LED types. Unlike Digital Current Control, which adjusts current at the pixel level when supported by the selected protocol, Color Intensity Scaling digitally scales pixel data before it is transmitted to the LEDs and can be used regardless of protocol support.

When a colour channel is scaled, its maximum available output is reduced proportionally. For example, scaling a channel to 50% reduces the maximum output value available to that channel. This can be used to correct channels that appear visually stronger than others, although it also reduces the number of available output levels for that channel. Firmware v3.14.0 also reorganises colour-related settings into a dedicated Pixel Color Tuning page.

Advatek recommends using Digital Current Control first where supported, followed by Color Intensity Scaling for additional channel balancing. Gamma Correction can then be applied to refine mid-level colour performance and fades, while Dithering can be used to improve visible smoothness on lower-resolution outputs. The company suggests keeping at least one colour channel at full scale where possible and reducing stronger channels to match, helping to maintain the widest available output range while improving colour balance.
