How would you plot, run a for loop, and a string at the same time?

Right now, I'm trying to plot 5 sets of data in 3 groups without having to retype the plots 15 times. Basically, I'm just trying to save lines of code. However, I also want to distinguish the 5 sets of data in each 3 groups by separating them by color and dots. This is what I have so far:

colors=[{'ro'},{'ko'},{'bo'},{'mo'},{'go'}]; 
figure(1) %p/patm vs x
for k=1:5
    hold on
    plot(L(1),pt_patm(6,k))
    plot(L(2:6),p_patm(1:5,k),colors(k))
end

L is a 1x6 Matrix; p_patm is a 5x5 matrix. I want the colors to change with each iteration. Instead, I'm getting an error that says

??? Error using ==> plot Conversion to double from cell is not possible.

Error in ==> fanno at 47 plot(L(2:6),p_patm(1:5,k),colors(k))

I get that this doesn't work with cell matrices. However, if I remove the '{}' brackets, colors turns into a 1x10) matrix which doesn't line up with the code that I have. Does anyone see a better way that changes 'ro' to 'ko' to (insert color/shape here)each time the code pulls out a different set of data?

change your cell format slightly

colors = {'ro', 'ko', ... etc }

then

plot(..., colors{k})

not

colors(k)

"[{'ro'},{'ko'},{'bo'},{'mo'},{'go'}]" and "{'ro','ko','bo','mo','go'}" are equivalent, but the later is nicer and faster.
