a) 256 × 256 image that have 256 colors on it starting 0 till 255 (the first column is black, the last column is white, and in between all the gray shades)

b) 256 × 256 image that have just 8 colors on it starting 0 till 7 (the first column is black, the last column is white, and in between all the gray shades)

You can use this code to generate the color rows:

clear all;
figure
for bits = 1:1:8
    Color=2^bits; %Number of colors level
    intervalo = 1/(Color-1); %intervales to each color
    C = zeros(Color,1,3); %To change rows by columns change this line zeros(1,Color,3)
    s = 1:-intervalo:0;
    C(:,:,1) = s'; % Red
    C(:,:,2) = s'; % Green
    C(:,:,3) = s'; % Blue
    subplot(3,3,bits);
    image(C); % C is mean of three channel (RGB)
    numeroBits =  num2str(bits);
    title({'\fontsize{12} Número de bits:' numeroBits});
    axis off;
end
