I am trying to create a character array for it to print a certain color out if a random wavelength is input, and it is giving me an error saying "Variable Spectrum has an incorrect value: You have not, or incorrectly, accounted for one of the colors. Incorrect spelling or capitalization could be a problem"

value = wavelength;
Spectrum = 'violet , blue , green , yellow , orange , red , Not Visible';
if  value >= 400 &&  value <450
    fprintf ('violet'); 
elseif  value >=450 &&  value < 490
    fprintf ('blue'); 
elseif  value  >=490 && value <560
    fprintf ('green'); 
elseif  value  >=560 && value <590 
    fprintf ('yellow'); 
elseif  value >=590 &&  value < 635 
    fprintf ('orange'); 
elseif  value >=635 &&  value <=700
    fprintf ('red'); 
else 
    fprintf ('Not Visible'); 
end
