Review on 🌈 ALITOVE 16.4ft WS2812B Individually Addressable LED Strip Light 5050 RGB SMD 150 Pixels - Waterproof IP67 - 2-Pack by Jeff Driscoll

These lights aren't bad but when controlled from Arduino using the fastLED library they tend to be VERY blue. The total luminous flux should be almost white - it's more like electric turquoise. I also tested by programming a rainbow on a strip that appeared as a single red pixel surrounded by some pinks and then a huge area of teal and blue. First I thought I didn't set the RGB order correctly, then I thought I had voltage issues and after exhausting everything else I turned to the setCorrection fastLED function. FastLED's suggested color correction for 5050 SMDs is 0xFFB0F0 (meaning 255 red, 176 green, 240 blue), which still looked very blue - until I rotated the blue and green very aggressively (0xFF6030 or 255 red, 96 green, and 48 blue ), the rainbow started to look like a rainbow. If you want your project to be bright and colorful, rather than just overly turquoise, you're going to need a significant amount of color grading.
