MATLAB: Want to create colors depending on the number of columns i got in the X

plot

Hello, i want to plot each column, and i want to associate each column with a color but automaticly.
X = [1:26]';
Y = [1:26]';
[n,m] = size(X);
rows = 3;
columns = ceil(n/rows);
extra_row = columns * rows;
X(n+1:extra_row) = NaN;
X_new = reshape(X,rows,columns)
So, if i put a different numbe ron "ROWS" my "X_NEW" will have more or less columns.
Question -> How to create a vector of colors or string of colors depending on the number of columns of X_new?
Thanks for your time

What about:
CMap = parula(rows)
