How can I have multiple colormaps in single map using mapping toolbox?

I have a map with pcolorm for nutrient depth (range 0-400m) and contourm for temperature (range 0-30 deg Celcius) contours. I would like to use two colormaps, 'winter' for nutrient depth and 'hot' for temperature. The image attached is almost correct, but I would like a range of color for the contour lines. The examples shown here haven't worked for the map axis: https://www.mathworks.com/matlabcentral/answers/101346-how-do-i-use-multiple-colormaps-in-a-single-figure

xq = lon2; yq = lat2;
x = NutMap(:,2); y = NutMap(:,1); v = NutMap(:,3);v2 = NutMap(:,4); %size(NutMap) = 129x161
vq = griddata(x,y,v,xq,yq,'linear');tq = griddata(x,y,v2,xq,yq,'linear');
vq(landmask(lat2,lon2))=NaN; tq(landmask(lat2,lon2))=NaN; 
contourmin = min(min(tq));
contourmax = max(max(tq));
pcolormin = min(min(vq));
pcolormax = max(max(vq));

colormap(hAxesP,winter);
