Fastled Library Goes slow

I develope a signal for certain ambiental values and will use WS2812B strip leds around a tube for 360 visualization.
I use 600 Leds (2 Strips), the first X leds is all green, next group yellow., orange,…violet.
The principal problem is the leds goes up one by one but slow (compared with some videos in Internet)…and hang-up the Photon…
The second problem is the color…I put Green but the leds go Red, I solved this last issue whit NEOPIXEL.
Any help willbe very appreciated.
Thanks in advance

There are different types of NeoPixels some use RGB others BGR or even more combinations (e.g. with a dedicated W LED).

Thay may be due to calling FastLED.show() after updating each individual pixel.
You’d normally first update all pixels and then call FastLED.show() once when done.
This will cause the update to become 600 times faster :wink:

Solved, yes it is I put the FastLEd.Show outside the loop and the things go Fast!!!
Thanks a lot!
