How to create the effect of light and notes on patterns

Hi everyone, how are you doing? I wanted to show these three journal pages today, this one here of a lamp shade and how easy it is to convincingly paint the effect of light. The light source, i.e., here the lamp , should always be the lightest area in the painting, I did this in a very pale yellow , anything too saturated will at the same time be darker, yellows and greens are most saturated at their light values, reds and greens at their mid tones and violets and blue in their dark range. A few touches of saturated color used sparingly though can enliven this effect of light. The shade is purple gray complementary to that of the light source. The side facing the source is lighter and warmer and the side facing away is darker and cooler.

Effect of light in painting

This one is another of my landscape color palette studies: Vertical planes like trees and houses should always be painted darker than the horizontal planes (ground) and inclined planes (mountains and slopes) when the sun is overhead. This is because the amount of light the ground receives will be more than that received by vertical and inclined planes. Mountains and hills are darker than ground but lighter than trees because their angle to the horizontal is somewhere in between 0° and 90°. When the sun is lower , for sunrises and sunsets, the rule holds in inverse. The sun rays will be hitting the trees and vertical planes directly and they will be lighter, the ground will be darker. The sky is an indirect source of light and will be the lightest (other than the sun). That`s the most important rule in landscape painting. Get that and the rest is a piece of cake! just kidding.. Who is your most favourite landscape painter, by the way?

This one is of notes I made while looking at various patterns occuring in nature. A pattern is a shape or motif that repeats itself. You can have lots of patterns, the most common in nature is what is called fractal, they are self replicating and look exactly the same at different scales. e.g., clouds, trees , coast lines etc. It is very interesting for me from a design point of view:
