RC4 ColorMatch™ makes it easy to calibrate color between multiple devices by visually matching white color temperature. This allows custom-built props to conform to the color palette of other devices, regardless of the light sources (usually LEDs) used.
When using the hue/saturation/level (HSL) color controller in RC4 Series 3 dimmers, variations in LED color becomes apparent. Some may appear warmer, others cooler; some may be too green, lacking enough blue, and so on.
Even LED sources that claim to be color-corrected or standardized may produce different color-temperatures of white, and this usually affects the entire color palette.
RC4 ColorMatch™ in the S3 dimmers provides a simple way to fine-tune color rendering. Each primary color — red, green, blue and, optionally, white — can be scaled, and this adjustment is applied constantly, in real time, ensuring that the desired color palette is smoothly rendered all the way around the HSL color wheel.
When building props using primary-color LEDs, it is difficult (often impossible) to match lumen output for each color. And each LED also requires a current-limiting resistor that must be sized appropriately for the voltage used, as well as the LED current draw and forward voltage. The ideal resistor is not always available, and the closest manufactured value must be substituted. The result is often one or more LEDs lighting slightly less brightly.
Viewed individually, small variations in brightness between primary-color LEDs is virtually unnoticeable to the human eye. But when color mixing is introduced, our eyes are remarkably sensitive to very small differences in color.
RC4 ColorMatch™ counteracts variations in LEDs, resistors, even mounting and diffusion, bringing the overall color experience back to a pleasing visual standard.
