This is water on a drizzly day.  Little contrast but still the tones follow the rules of reflection - less darker and less lighter than the reflected object.  Notice the boat reflection colour is much duller than the actual.  White paper is left unpainted in little slivers to provide the sparkle of light where water meets solid objects.

"Still water can be painted in two parts.  Firstly a wash that, using wet in wet colours, reflects the sky colours and gives the appearance of a gentle rise and fall of the surface.  When dry either reflections are painted in or further sky reflections are painted which represent the few ripples."

"Simplify, simplify.  A few wobbly brush strokes and marks can show the complexity of the various ripples and colours reflected".

"Water, just like skies. provides the chance for the watercolourist to show fluffy edges alongside hard edges - an attractive use of the medium".
