Build a background that does less
Flat color can carry an entire composition when contrast, crop, and texture are treated as deliberate choices.
design
A minimal background works when it is treated as structure rather than absence. Flat color directs attention, creates instant recognition, and gives type room to become the image.
Contrast before decoration
Choose the relationship between background and type first. If the words are hard to read at thumbnail size, texture will not rescue them.
Empty space is active
Moving the line slightly off center or letting a short word sit alone can create more personality than adding another visual element.
Export for the destination
A square is versatile, a vertical canvas owns more phone screen, and a landscape image suits link previews. Compose at the target aspect ratio rather than cropping as an afterthought.
