How do I make an If statement for retrieving a colour from pixel values

I have a range of pixel values that I have for the indiviual squares and mate a range of these values that when I get the pixel value for a specific point it should return the colour of the original image before I converted it to grayscale but it keeps giving me the wrong colour each time?And help would be greatly appreciated

    img = imread('noise_1.png'); % Read file
    I = im2double(img);% Convert image to double data type 
    
    N = imnoise(I, 'salt & pepper', 0.03); % Add noise to the image
     
    red_channel = N(:, :, 1); % Separating red channel
    green_channel = N(:, :, 2); % Separating green channel
    blue_channel = N(:, :, 3); % Separating blue channel
    
    Ravg = mean2(red_channel); % Mean of red channel
    Gavg = mean2(green_channel); % Mean of green channel
    Bavg = mean2(blue_channel); % Mean of blue channel 
    
    disp('Average of red channel:');
    disp(Ravg);
    disp('Average of green channel:');
    disp(Gavg);
    disp('Average of blue channel:');
    disp(Bavg);
    
    % 2-D median filtering
    red_channel2 = medfilt2(red_channel, [3 3]); 
    green_channel2 = medfilt2(green_channel, [3 3]);
    blue_channel2 = medfilt2(blue_channel, [3 3]);
 
    F = cat(3, red_channel2, green_channel2, blue_channel2); % Concatenating the channels along 3 dimensions 
    
    grey_scale = rgb2gray(F) % Converting RGB image into greyscale
    
    h = imshow(grey_scale);
    hp = impixelinfo;
    set(hp,'Position',[5 1 300 20]);
    
    wow = grey_scale(200, 200)
    
    if 0 <= wow <= 0.53,
       disp('Blue');
    end
    
    if 0.54 <= wow <= 0.75,
       disp('Red'); 
    end
 
    if 0.75 <= wow <= 0.89,
       disp('Green');
    end
    
    if 0.89 <= wow <= 0.96,
       disp('Yellow');
    end
     
    if wow > 0.97,
       disp('White');
    end
