Modern decorative clocks are usually those clocks that are artistically crafted yet follow the minimal lines that modern art often follows.
Majority of modern decorative clocks people can find on sale are often made in abstract shapes, simple geometrical compositions or simple shape combinations with a splattering of a huge number of colors.
There are modern decorative clocks that are made in a sunburst shape in a single color, all of these are available in your local clock dealers and manufacturers, with the hands of the clock usually in a contrasting shade to make them stand out.
There are also modern decorative clocks that sport the usual square, rectangle or circular shape a lot of clocks are known to come in but are artistically colored with either an abstract painting on this rather common shape or may come in a few combined shapes in different colors to give the clock its artistic appeal.
