This is the code i am using and it is working fine with MyS 1.5.1 and Domoticz 3.5877.
/*PROJECT: MySensors / RGB test for Light & Sensor
PROGRAMMER: AWI/GizMoCuz
DATE: september 27, 2015/ last update: October 10, 2015
FILE: AWI_RGB.ino
LICENSE: Public domain
Hardware: Nano and MySensors 1.5
Special:
uses Fastled library with NeoPixel (great & fast RBG/HSV universal library) https://github.com/FastLED/FastLED
Remarks:
Fixed node-id
Added option to request/apply last light state from gateway
Domoticz typicals - 2015 10 10:
- Domoticz is using HUE values internally, there might be a slight difference then using direct RGB colors.

When you get the RGB Light in Device, add it and edit the Device to be a Dimmer instead then click on the three cubes and start to select the color you like
