Do you mean exactly same values in red and blue lines? You can do:
same_values = find(blueline==redline); % gives same samples
percentage_of_red_in_blue = (100*numel(same_values))/numel(blueline); % gives percentage of red in blue

do you mean the ratio of the volumes under the lines? You can easily calculate it with
percentage_of_red_in_blue = 100 * sum(red) / sum(blue);
if both curves have the same discretised x-values
