Hi,
I bought this strip: WS2811 5050 SMD RGB and I need to adjust color temperature. What value do you suggest? This is best I found so far: .setTemperature(0xFFA861)

There’s a bunch of presets you can try. I made this example to cycle through them.

#include "FastLED.h"
#define DATA_PIN    11
#define CLOCK_PIN   13
#define LED_TYPE    LPD8806
#define COLOR_ORDER GRB
#define NUM_LEDS    32
#define BRIGHTNESS  255
CRGB leds[NUM_LEDS];

#define DISPLAYTIME 4  //number of SECONDS to show each color temperature
#define BLACKOUTTIME 100  //number of MILLISECONDS to blackout between tempatures
uint8_t temp;  //current tempature_# being displayed

Also, you can manually dial in a color correction using .setCorrection which would be added like this:

FastLED.addLeds<LPD8806, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS).setCorrection(255,128,196);

This (extreme) example would leave red un-touched, reduce green by 50%, and reduce blue by 25%.

@marmil Great script! Thank you. I found this combination as best: Correction - TypicalSMD5050; Temperature - Candle. Is it important which correction is first? For now it’s: FastLED.addLeds<WS2811, LED_PIN, BRG>(leds, NUM_LEDS).setCorrection( TypicalSMD5050 ).setTemperature( Candle ); but maybe is better (for color, or calc speed… etc) to put: FastLED.addLeds<WS2811, LED_PIN, BRG>(leds, NUM_LEDS).setTemperature( Candle ).setCorrection( TypicalSMD5050 );
