Is it possible to make colored lights in indigo?

Like Christmas lights?

Maybe by editing xml?

he achieved some interesting colored-light results playing around with tonemapping. Check the end of the page.

Encapsulate your emitter in a colored transparent hull. For example, create a UV sphere, set it to emit. Then create another, slightly larger sphere around the emitting one and set it to transparency with an IOR of 1.

easier still...

Code: Select all

<meshlight>
  <pos>---whatever-</pos> 
  <scale>1.0</scale> 
  <rotation>
    <matrix>---whatever---</matrix> 
  </rotation>
  <mesh_name>ColouredEmitter</mesh_name> 
  <spectrum>
    <rgb>
      <rgb>0.4 0.0 0.0</rgb> 
    </rgb>
  </spectrum>
</meshlight>

and use an RGB value

But remember that RGB lightning has no gain value, and is very very very (!!!) weak
compared to Black Body Lights, HDRI Lightning etc.
So Rainhard will kill all lights if you don't tweak other lightning very well,
or simply use RGB lightning for every light else you use in the Scene

You can crank up the components for a RGB light over 1.
500 250 0 is fine.
