Create an RGB Image using a loop by choosing a random color for each pixel

I what to create an RGB image as for every iteration of the loop it chose a differencet color for that particular pixal.

What I have right now only generates a new image after each iteration. So I end up with 10 images of a black square.

What I want my code to do is to create a image that chosses a random number for each pixal.

x = 1:10
y= 1:10;
image=zeros(10,10,3)
m = randi(3,10,1)   % creates a vetor that of random numbers from 1:3 that deterimes what color to chose for each pixal.
%count = 0;            % was having trouble generating the random number in the loop, so I just put it outside.
for i = 1:10
    for j = 1:10
    
    n(k) = m(i)
if n(k) == 1 
 image(x(i),y(j),1)=0;  
 image(x(i),y(j),2)=0;    % if the random number is 1. This pixal will be black 
 image(x(i),y(j),3)=0;  
 
 if n(k) == 2
 image(x(i),y(j),1)=250;   
 image(x(i),y(j),2)=0;    %if the random number is 2. This pixal will be red
 image(x(i),y(j),3)=0; 
 
 % repeated code for blue
 % I would want to have the pixal be Red, Black, or blue
 end
end
 
end
%figure;
    imshow(image)
end

x = 1:10;

y= 1:10;

image=zeros(10,10,3);

m = randi(3,10,10); % creates a vetor that of random numbers from 1:3 that deterimes what color to chose for each pixal.

%count = 0; % was having trouble generating the random number in the loop, so I just put it outside.

for i = 1:10

for j = 1:10

if m(i,j) == 1

image(x(i),y(j),1)=0;

image(x(i),y(j),2)=0; % if the random number is 1. This pixal will be black

image(x(i),y(j),3)=0;

elseif m(i,j) == 2

image(x(i),y(j),1)=250;

image(x(i),y(j),2)=0; %if the random number is 2. This pixal will be red

image(x(i),y(j),3)=0;

elseif m(i,j) == 3

image(x(i),y(j),1)=0;

image(x(i),y(j),2)=0; %if the random number is 3. This pixal will be blue

image(x(i),y(j),3)=250;

% I would want to have the pixal be Red, Black, or blue

end

end

%figure;

imshow(image)

How would I create a larger image? It is 10 x 10 right now, but I would like it 400 x 400

Just realized what to do. Thank you

no te sirve así?

for i=1:10
imagen=uint8(randi(255,10,10,3));
figure
imshow(imagen)
end

Sí, pero quiero usar un loop porque Quiero que el color del pixal sea determinado por una función.
