How can I use NN & CNN for RGB images?

Hi, I have a problem for the NN & CNN. Please help me! One row of the sample data MNIST indicates as a handwritten numeral. Each handwritten numeral is a gray image (one band). But my training datas are lots of RGB images (three bands). How can I use NN & CNN for RGB images?
One way is to convert the RGB images to gray scale Or re-write the code to support RGB images. By the way RGB images dont make sense. So just convert them to grayscale using Matlab functions :)
hye!
I need some help regarding Matlab.
From the point cloud 3D data I have to extract specific square area for which i know only 2 corner information i.e upper left x,y,z coordinate and bottom right x,y,z coordinates.
For this i've to apply some codes in MATLAB through which i get my area of interest(AOI) i.e specific square area which i mentioned above.
could you please check my code.Because there accour an error.
M= dlmread('sample_data.txt');
x= -7.836000;
y= 20.534000;
z= 4.541000;
x1= -7.095000;
y1= 20.013000;
z1= 4.675000;
discard = M(:,1) < x(1) | M(:,2) < y(2) | M(:,3) < z(3) | ...
M(:,1) > x1(1) | M(:,2) > y1(2) | M(:,3) > z1(3) ;
Y(discard,:) = [];
Thanks.
