LIGHTHOUSE & FRIGATE

It's easy to draw however it is the coloring that I am fickle-minded. Do I like blue or red or just pastel colors or something out of the ordinary? 

Then I settled for this blue lighthouse  because not all lighthouses are red colors like a fire hydrant. 

Some lighthouses are "yellow" wanting to be seen.
 

Lighthouse with spiral staircase outside instead of inside.

 Is there a lighthouse in the Arctic?
