The fine line that separates art from graphics leads you to think that the latter is nothing other than a question of taste. As the saying goes “we don’t discuss tastes and colours”. This may be true when it’s about appreciating a work of art; however, it doesn’t apply to the creation of graphic design that must convey a precise message. In fact, despite the many different possible styles, a design must be precise before being “beautiful”.
Shapes and colours each have their own meanings, so you must use them wisely.
