If statement for array

I wrote this code in Matlab to get the color "rgb numbers" of a apecific pixel for each frame of a video:

video=VideoReader('TS_Example_2.mp4');
vidHeight=video.Height; 
vidWidth=video.Width;
c = 182; 
r = 84;
k=1;
while hasFrame(video)
    img = readFrame(video);
    rgb(:,:,k)=impixel(img, c, r);
    k = k+1;
end
out=rgb(:,:,:)

I got an answer for all 866 frames like:

out(:,:,1) =

   255   255   255


out(:,:,2) =

   255   255   255


out(:,:,3) =

   255   255   255
.
.
.
out(:,:,864) =

   210     3    16


out(:,:,865) =

   210     3    16


out(:,:,866) =

   210     3    16

Now, I would like to write few lines to check if the colors during any frame is within specific range. I started by trying a specific frame "866" and specific rgb "210,3,16", but it didn't work. I wrote the following:

if rgb(:,:,866) == [210 3 6]
    disp('Value within specified range.')
else
    disp('No')
end

And I got the answer "No", while it's supposed to give "Value within specified range"!

Can anyone tell me where I went worng?

I also appreciate helping me to write few lines to check if the colors during any frame is within specific range

out(:,:,866) =
   210     3    16
[...]
    
if rgb(:,:,866) == [210 3 6]

866 has B component 16. You are testing for B component 6. Not a match.
