Hello everyone, how can I label each colour

for example in the following picture, each colour label on the side of the graph.

clc; clear
k=0.5;den=1600;cv=725;aLf=k/(den*cv);
L=0.4;td=12*3600;
Ts=20;Ti=10;
nx=60; nxp=nx+1; dx=L/nx; 
nt=6;ntp=nt+1;dt=td/nt; 
x=linspace(0,L,nxp);T=zeros(1,nxp);
depth(1)=0; 
for i=1:nt
time(i)=(i)*dt;
for j=1:nxp;
  depth(j)= j*dx;
  if j==1;
      Tx=Ts;
  else
  Tx=Ts+((Ti-Ts)*(erf(depth(j)/(2*sqrt(aLf*(time(i)))))));
  end
  T(j)=Tx;
  TM(i,:) = T;
end 
plot(x,TM,'linewidth',2);hold on; 
xlabel('Depth from surface(x)');ylabel('Surface Temperature(Ts)');grid on
end
