I am trying to plot a "butterfly curve" with the two formulas:

I got the plot to run, however, I would like x to be the color blue and y to be the color red. I cannot get the two seperate colors to show up for each variable. Here is my code:

clc
t=0:(0.0625):100;
ev=exp(1); %just the constant e 
for i=1:2
    hold on
    x=sin(t).*(ev.^(cos(t))-(2.*cos(4*t))-(sin(t/12).^5))
    y=cos(t).*(ev.^(cos(t))-(2.*cos(4*t))-(sin(t/12).^5)) 
    plot(x,y)
end

clc

t=0:(0.0625):100;

x=sin(t).*(exp(cos(t))-(2.*cos(4*t))-(sin(t/12).^5));

y=cos(t).*(exp(cos(t))-(2.*cos(4*t))-(sin(t/12).^5));

%plot(t, x, t, y)

plot(x, y)

Thank you for your reply. However, I believe it's supposed to maintain the shape of the "butterfly curve". I want to separate x and y completely but keep the same form - and create a color legend based on it.
