It's a vector variable so you write it:
lamMAT_matrix.color = << r, g, b >>;

where r = red, g = green and blue ranging from 0 to 1.
Black would be << 0, 0, 0 >>, white would be << 1, 1, 1 >> and mid green would be << 0, 0.5, 0 >>. Get it?

HEllo! First, thanks for your help ...
i did it befor that way as well, because i found this expression for a vector in the maya help, but it tried it and maya gave me this answer (to the exact same line you wrote) :
"Error: Attributes must be of float, integer, or boolean types: color" ...
and thats what i donīt get ...the rest i am familiar with from photoshop.
do you have any idea why maya doesnīt accept that line ?

Uh... I talked BS before :p
It's not a vector variable. It's a float3. You also (may) need to use the setAttr command:

setAttr lambert1.color 1 1 1;

Sorry, my bad...

In an expression, you set the R, G, and B like this:

lambert1.colorR = 0;
lambert1.colorG = 1;
lambert1.colorB = 0;

You can connect another float3 attribute to lambert1.color, which is a compound attribute that includes colorR, colorG, and colorB.

Look in the Node and Attribute Reference to see this stuff -- these attributes are listed on the page for the Lambert node.
