If you have noticed discrepancies in the colors of your lights, it is most likely related to power. If LEDs are not getting sufficient power, they will be more red. This is most noticeable when setting the colors to white, since it uses the most power. Follow the steps below to fix any color discrepancies.
Check your power injection points
If see a very noticeable difference in the colors of your lights, particularly with large sections of lights, it is most likely because a power injection point near that section is not done correctly.
- Unplug your controller box.
- Verify all of your power injection points are done correctly according to the instructions.
Change the current limiter in WLED
Sometimes adjusting the maximum current in the WLED settings can help. It will lower the overall brightness, but the colors will be more accurate.
- Go into the WLED app.
- Go into Config > LED Preferences
- Lower the "Maximum Current"
- Tap "Save"
This can also be tested by lowering the brightness. If lowering the brightness helps produce more accurate colors, then you should turn down the maximum current in the settings.
Use a warmer white
Since white uses the most power, using a warmer white will most likely fix any color discrepancies. There is already a warm white preset in WLED. It's the tan-colored one next to the white.
It might be the angle of the LEDs
Each LED is actually composed of 3 smaller LEDs: a red, green, and blue (RGB). Because of this, the colors of the LEDs might vary a bit depending on the angle. This should really only be noticeable if you're very close to the LEDs, so it's unlikely this is your problem if you are seeing wrong colors from a distance.
