Hey guys,
I'm just trying to get my head around the RGB tristimulus graph, as follows:

Why are there negative values for red? What does it mean?
I'd appreciate it if someone could help. And no, this isn't a homework question, it's part of my...

KCL
The Attempt at a Solution
I recognise that the voltage sources form supernodes. This produces:
A - B = 10 -> A = 10 + B
We also know that node C is 12v.
I then form KCL equations:
6 + \frac{A - C}{12} = \frac{B}{40} + \frac {A}{24}
When I...
Look up 'supernodes'. Basically, the nodes on either end of the voltage source combine into a single node. If the nodes are, for example, A and B, and the voltage souce between them 12v, then:
A - B = 12v (where A - B just means "the voltage difference between A and B")
Since A and B are...
