No subject means nothing to argue with.

Where it comes from

Abstraction as a deliberate programme starts around 1910 with Kandinsky, Hilma af Klint and Malevich, each arguing that a painting need not depict anything to mean something. The decorative abstract we see now owes more to what came after — Rothko's colour fields, Albers's nested squares, and the hard-edge painters of the 1960s. Those are the ancestors of nearly every abstract print sold today.

What makes it that style

• No recognisable subject. Shape, colour and balance carry the whole thing.
• Colour relationships rather than colours. How two tones behave beside each other matters more than either one alone.
• Composition you can feel before you read. Weight, tension and balance land immediately, which is why abstract works at a distance.
• Enormous range. From three flat blocks to dense gestural paint — 'abstract' describes what it isn't more than what it is.

Which rooms it suits

Anywhere, genuinely. It is the safest choice for a room you are unsure about, and the best choice for a room with a strong existing palette you want echoed rather than matched.

Framing

Whatever the room already uses. Abstract is frame-agnostic — which is a real advantage if you own frames already and would rather not buy more.

The mistake worth avoiding

Choosing on colour and forgetting scale. Because the colour matching is so satisfying, people stop there. But an abstract with three large shapes needs size to work — shrink it to A4 and the shapes become fussy detail, which is the opposite of the intent. Dense, detailed abstracts can go smaller. Bold, simple ones cannot.
