MATLAB: Switch-case function problem

caseswitch

Hello, I am trying to get the values of the vector color to be displayed as 0 = yellow; 1 = red; 2 = green;
3 = blue; using switch-case function. I got this but it doesn't work.
color=[2,1,3,0,1,3,1,0,2]
cName ={'yellow','red','green','blue'};
for ind=1:length(color)
switch ind
case color ==0
disp(cName{'yellow'});
case color==1
disp(cName{'red'});
case color==2
disp(cName{'green'});
case color== 3
disp(cName{'blue'});
end
end
Could someone help me with this?
THANKS!

First variation: fix the switch and case lines and the indexing into cName.
    switch color(ind)    
        case 0
            disp(cName{ind+1});
        case 1
            disp(cName{ind+2});
Second variation: dispense with the switch statement altogether.
color=[2,1,3,0,1,3,1,0,2]
cName ={'yellow','red','green','blue'};
for ind=1:length(color)
    disp(cName{color(ind)+1})
end
Third variation: use a string array instead of a cell array of char vectors. This is the modern way to handle text in MATLAB.
color=[2,1,3,0,1,3,1,0,2]
cName = ["yellow", "red", "green", "blue"];
for ind=1:length(color)
    disp(cName(color(ind)+1))
end
