How do I add more lights to brighten up the left wall? And how do I get a
lighter shade of the khaki that I'm using. Here's my code:
#include "colors.inc"
background {color White}
light_source{
0*x
color White
area_light
<8,0,0> <0,0,8>
4, 4
adaptive 0
jitter
translate <40,80,40>
}
camera {
location <0, 0, 11>
look_at 0
angle 40
}
// Right Wall
box{
<1,1,1>,<-1,-1,-1>
texture{
pigment{
color Khaki
}
normal{
wrinkles 0.25
scale 0.005
}
finish{
ambient 0.266167
diffuse 0.884867
}
}
scale <0.1, 1.5, 3.5>
translate <-2.938508, 0, .140896>
}
// Left Wall
box{
<1,1,1>,<-1,-1,-1>
texture{
pigment{
color Khaki
}
normal{
wrinkles 0.25
scale 0.005
}
finish{
ambient 0.266167
diffuse 0.884867
}
}
scale <0.1, 1.5, 3.5>
translate <2.938508, 0, .140896>
}

to brighten this light you can multiply the color by a number
i.e., White*1.5, White*5, etc...

Again, use multiplier to change the intensity of the color ( <1=darker,
>1=lighter, i.e. try Khaki*1.1) this is a quick change for opaque colors,
remember that the multiplier will affect the transmit and filter values as
well if they are greater than 0

You can have more than one light source in a scene. Or you can specify
color White*1.5
to make your exsiting one brighter.

Again, you can multiply the color by a constant, e.g.
color Khaki*1.5
or also do calculations with it:
color 1-(1-Kahki)*0.5
which will reduce the difference between Khaki and White. You could also
play with the ambient and diffuse values, which will actually not change
the color but the way how the surface reacts on the incoming light.
