How do I obtain a composite of two grayscale images?

I want to make a composite of two images with "imfuse" function as follow:

imfuse(A,RA,B,RB,'ColorChannels',[1 2 0])

Is there anyway to make the Colorchannels "off"

What do you mean 'Off'?

What are you starting with, gray scale or color images, and what do you want to end up with? http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

The images that I started with are gray scale. I want a gray scale image as the output as well. In the output image, I see green-magenta color which is related to imfuse command (The colorchannels part). I try not to have the green-magneta color in my final images.

Do you just want to average the two images?

Have you tried this:

[C,RC] = imfuse(A,RA,B,RB,'blend');
