Can you change individual elements in a for loop each time?

Is it possible to change something non-numerical inside a for loop each time it goes through? I'm trying to make a different colored line on a graph every time it loops. If that's not possible, I'd love to know what else I could do to achieve the result.

To have some code to tweak I suppose it could be something like the following, but I'm trying to have each value of 'x' as represented on the graph a different color (first loop (1,5) a black circle, second (2,5) a red one, third (3,5) a blue, etc).

clc;clear;close all

figure

hold on

for x=1:10

y=5;

plot(x,y,'ko')

end

clc;clear;close all
figure
hold on
col = {'ro','bd','k+'}

col = 1×3 cell array
    {'ro'}    {'bd'}    {'k+'}

col1 = {'r-','b-','k-'}

col1 = 1×3 cell array
    {'r-'}    {'b-'}    {'k-'}

% plots points 
for x=1:3
y=5;
plot(x,y,col{x});
end

figure
hold on
% plots lines
n = [0.5 1 1.5];
for x=1:3
X=1:10;
plot(X,X.^(n(x)),col1{x});
end

Works great, thank you!
