This defines the maximum brightness of each channel. In this scenario that's 450bytes of data, which is roughly 25% of an Arduino Unos ram, entirely dedicated to 3 bytes worth of data: one single color. Oh hey- question about the named colors: we pulled the color definitions from an HTML standard somewhere, but now that I see some of them on LEDs, they don’t look “right” to me, because, I suspect, the hex values are intended to be used on a gamma-corrected output device, and raw LEDs aren’t gamma corrected. So I tested all predefined color temperatures. Most leds are bright white or washed out colors. I'm wondering if is there some function to mix the brightness and color bytes to make the low light passage smoother. 20 // (2) master control of the overall output 'color temperature' 41 // FastLED provides these pre-configured gaseous-light color profiles: 42 // WarmFluorescent, StandardFluorescent, CoolWhiteFluorescent, Consequently I assume this colorIndex value refers to the index of the color in the final stretched 256-color palette and by jumping 3 colors we essentially fit palette of 256 colors into roughly 85 LEDs (256/3=85.

Is there a method to apply a one time correction value to specific LEDs? FastLED. 0 Then i looked into color correction in fastled and found this : Color correction-temperature. CLEDController & setTemperature (CRGB temperature) Set the color temperature, aka white point, for this controller. Definition at line 543 of file colorutils. FastLED gives you many ways to specify a color for an LED. 0 release page Oh, and just for the record, I was also using the FastLED color correction on the LED strip: setCorrection( TypicalLEDStrip), which tends to cut the green power a bit. Contains definitions for color correction and temperature. 86 FastLED the source array, containing color indexes for the palette : dataCount: the number of data elements in the array : targetColorArray: the LED array to store the resulting colors into. setBrightness( 0. CLEDController & /// Calculates the combined color adjustment to the LEDs at a given scale, color correction, and color temperature /// @param scale the scale value for the RGB data (i. I've simply hard-coded a hue value, which produces an orange color in my LEDs. brightness) /// @param colorCorrection color correction to apply The power limiting functions don't take the color correction and color temperature adjustments into account. 0 release page; New Designer Color Palettes for FastLED There’s a great web site for color designers called “cpt-city” (short for ‘color palette city’) that has page after page of pre-designed color palettes, for all kinds of things from art to science, maps to video games. g.
