MATLAB: While Loop is not ending, just keeps repeating from top

guessing gamewhile

I am trying to create a guessing game where the user chooses from 3 colours, this is my script so far.
colour = {'Red','Green','Blue'}
x=colour{randi(numel(colour))}
guess = 0
while guess ~= 1
      guess = input('Guess the colour, is it Red, Green, or Blue? ','s')
      if(strcmp(guess,x)==1)
          continue
      else
          display('Incorrect')
      end
  end
  display('Correct')
Forgive my lack of not knowing how to organise this post a little better and thankyou in advance for your answers.

Best Answer

Some slight changes:
colour = {'Red','Green','Blue'}
x=colour{randi(numel(colour))}; % <-- Added semi-colon so you don't print answer
% guess = 0  <-- don't need this
while( true )  % <-- changed condition
      guess = input('Guess the colour, is it Red, Green, or Blue? ','s')
      if(strcmp(guess,x)==1)
          break; % <-- changed continue to break
      else
          display('Incorrect')
      end
  end
  display('Correct')
