Troubleshooting
Colours are wrong (red is green …)
3 checks, sorted by how often they are the cause. For all WLED controllers with ESP32.
Check in this order: the most common and simplest cause comes first. Usually the cause is found after two or three steps.
Most common cause
Colour order LED Preferences → Color Order. WS2812B is usually GRB. Just try RGB, GRB, BRG until red is really red.

RGBW set correctly?
Set RGBW strips (e.g. SK6812 RGBW) as an RGBW type and choose an auto-white mode under White Management. Otherwise colours shift from the second LED on.
White has a tint?
Keep gamma correction on. Yellowish towards the end is not a colour issue but voltage drop (see the next symptom).
Safety
Disconnect the PSU from mains before working on cables. Work on the 230 V side only by a qualified electrician.
