The horizon will appear the lightest (whitest)...
The sequence of events is thus ...
1.The whole scene is painted with a red/blue.(color
at the top)
2.Beneath the horizon an additional marine
(cerulean) blue is added.
Water usually appears a little (half value
or more) darker than the sky.
3.Successive layers of mist are placed between
the viewer and the scene - the greater the distance the more the layers.

As the water shallows, yellow sand adds a veil
of green. The veil of green is added to the bottom foreground.

Now we can add some boats. They are identical
- only the second is minimized to allow for distance - and then placed
behind four layers of atmosphere.
STUDENT ACTIVITY: Using strips of cellophane (semi-transparent) paper and two small cut out 'images' construct an atmospheric 'collage' as I have done. Allow 40min.
