Sorry, only just seen this:

As always there are a number of ways of doing this. Basically to
achieve
this you need a light source, and a movable gel (coloured film) You
could
then rotate the gel in front of the light source at a chosen speed, and
the
wall will change colour. (ideally the gels would be on a graduation
basis,
to provide the movement of colour) (or a number of gels that could be
mixed
together)

You can do it this way, IMHO this can look odd, as the light source
will
appear to move.

It does, it depends on the colours you wish to change between, as
depending
on how dark the colour is will directly change the amount of available
light
in a room.

Unfortunately not, you would find it difficult to mix the colours in
this
way, as the bulbs will be in different places, and mixing light is very
difficult!!

Take a look at www.Martin.dk for some wonderful lighting products.
(robocolors would offer this kind of effect)

Also have a look at optikinetics, these may well be able to do what you
are
after. http://www.optikinetics.com/IndexA.htm

Also depending on how you want the effect to look, Fibre Optic lighting
would do this kind of effect.

Wondering if anyone out there knows the best way do the effects where
you wash a wall with light and then adjust the colour of the light.

I assume you need light sources of different colours which you then
ramp
up and down to acheive the desired effect. 

But how do you keep the level of light consistent? If using three
colours I suppose you could set the max level to be one source full
on....then if you increase colour A by X you decrease B and C by half
X,
does this make any sense?

Final question would it be possible to use two colour rope lights to do
this so for example you could have a red/white rope and a blue/green
rope. You use the white to boost brightness/intensity and the other
three to produce the specific colour you want. have the whole thing
shining through a difuser. Would this work or am I talking total
twoddle;)
