Some light effects on SL

On Secondlife i created three sphere and made them emit three different lights : Red, Blue and Green.

As you can see, there is white light in the center where my avatar is standing while there is a range of colours around it.

Here is my colour according to the day month and year of my birthday.

I believe i am a Bluey sort of colour.

Some information of colour types:

Additive colour: is a combination of emitted lights that create the sensation of a range of colours. Typical colours used are red, green; blue.

Subtractive colour: By removing a colour from white light e.g. red removed from white leaves green and blue to create magenta.  Mixing colours and subtracting from white creates new colours.
