All abstract is nice, but it should have a message!
For example a message of colours transmitting impressions like:
- the colours of sea shore,sand, sea waves, the warmth of the sun,…..
- the colours of spring, rebirth of nature can be expressed in colours
- the shadow and coolness of a forest can be described in colours
There could be more examples but I think the necessity of a message in the abstract painting should be sufficient described.
