Changing colors in scatter plots?

Greetings all,
I was trying to somehow change colors of a scatter plot I have of two values.
What I started off with was this:
scatter(ModelFile(:,4), z_i_1_abs)
where the "x" value - ModelFile(:,4) has 1156x1 values, and the same for the "y" value - z_i_1_abs - it also has 1156x1 values. This line plots succesfully, but I want ModelFile(:,4) to be one color and z_i_1_abs to be a separate color. When I plot it now, both are blue.
So I looked at gscatter and the good old plot command, and I tried hold on, but I just keep getting errors.
Any advice?
Thanks!

I'm not sure what you think you want, but perhaps:
dotsize = 10;
n = length(z_i_1_abs);
scatter( 1:n, ModelFile(:,4), dotsize, 'b');
hold on
scatter( 1:n, z_i_1_abs, dotsize, 'r');

We wouldn't normally think of that as a scatter plot.
Another way of accomplishing the same thing would be:
plot( [ModelFile(:,4), z_i_1_abs(:)], 'o')
This can be extended to any number of columns, but each column must be the same size. (Also, colors would start to repeat after the 8th column.)
