Hi Vivien,

Welcome to the forum!!

The PI has an onboard Polyfuse that will increase its resistance to a level where it isnt allowing much current.  
You’ll be able to power a small strip off the 5V GPIO (about 5 at full brightness or 15 at a reasonable brightness).  
Also note that the LED’s will draw current even when they’re not lit!

There’s a middle ground where the WS2812’s are receiving a lower than expected voltage and there is a noticeable redshift @Liam120347 has a good photo here: [12 day project: ESP32 - LED controller - #6 by Liam120347](https://forum.core-electronics.com.au/t/12-day-project-esp32-led-controller/12926/6)

Let us know how you go!
