The LEDs fade between colours, however, not quite the colours described. With 3.3V or CR2032 battery, the LEDS fade as follows: Red, Bright Green, Blue, Pale green, Turquoise, Purple, Pale turquoise and then the cycle starts over. With other colour fading LEDs I bought elsewhere, the colours were more evenly matched in brightness and included yellow and white in the colour fading cycle.
