Visual solution

Solution without words by David Andriana.


Composition in red blue
and yellow
Like a Mondriaan
An artist interpreting partly
Work and stylistic
A yellow blue red composition
Looks like Mondriaan’s image language
Like creating a modern utopia of reality
Colours and forms are primary
And strait lines for order in humanity
