Variable illumination is a function that adjusts the light output applied to each colour on the colour wheel. Increasing the amount of light on the R (red) portion of the colour wheel, for example, has the same effect as increasing the size of the red area on the wheel. Using variable illumination, a variety of colour balance modes can be created without having to change the colour wheel itself.

This technology controls the color balance for different applications by adjusting the amount of lighting directed at each of the color wheel. The balance of color can be adjusted by choosing the color modes on the projector.

BrilliantColor™ technology from Texas Instruments® PS200 Series offers a wide choice of software-based color modes. Each mode is achieved by adjusting the illumination  on different segments of the color wheel. Users can choose the optimal color balance to suit their projecting needs. Mitsubishi SD510U SVGA Projector also introduces new variable illumination technique makes selected colors more vivid by adjusting the lamp power while maintaining all the brightness of your mobile projector.
