The six RGB-CMY circles represent 6 parasols which cumulatively (overlapping each other) form a MonoSol - not a good solution tho' - too Tho' these six are not not a feasible solution, they do form a graphic framework for the better Lenti-Sol solutionThe six brown circles represent 6 parasols which cumulatively form a LentiSol (aka 'Annulus')The six brown plus 6 grey circles represent 12 parasols which cumulatively form a LentiSol (aka 'Annulus')
