A visual identity is the system of visual elements that makes a brand recognizable across every surface it appears on: logo, colour, typography, imagery, layout logic, and motion.
The word doing the work is system. A logo is not an identity. An identity is what lets someone recognize the brand in a photograph with the logo cropped out, which is a much higher bar and the only one that matters in feeds.
The components
Logo and its lockups. The least important component and the one clients discuss most.
Colour. With proportion, not just values. Which colour dominates and which appears rarely is more identifying than the palette itself.
Typography. A hierarchy, not a font list: what a headline looks like, what body text looks like, what happens at small sizes.
Imagery style. Photographic or illustrative treatment, framing conventions, how people are shot, how products are shot. Usually the strongest recognition signal and the least documented.
Layout logic. Grid, margin, how much space is left empty. Brands are frequently recognizable by their whitespace alone.
Motion. How things enter, how fast, with what easing. Increasingly part of identity rather than an afterthought, because most brand exposure now happens in video.
Sound, for brands that appear in video and audio: a sonic mark, a music direction, a voice.
Visual identity vs branding vs brand guidelines
Branding is the whole strategic apparatus: positioning, values, voice, and behaviour. Visual identity is the visual subset. Brand guidelines are the document that specifies it.
Most confusion comes from teams commissioning a logo, calling it a rebrand, and then wondering why the work does not look coherent.
The recognition test
Take three pieces of the brand's recent work, crop out every logo, and show them to someone familiar with the category. If they cannot attribute them, the identity is a logo and some colours.
Brands that pass usually pass because of imagery style and layout, not because of the mark.
Examples
A DTC food brand. One dominant warm neutral with a single accent used sparingly, a grotesque at three weights, overhead-on-wood photography with hands present, and generous margins. Recognizable at thumbnail size with no logo visible.
A software brand. Illustration-only imagery in a fixed palette, no photography of people at all, tight grid, motion that always enters from below. The exclusion of stock photography is doing as much identity work as anything included.

What is a brand board is the one-page summary teams actually use. What is art direction covers applying an identity to a specific piece. Brand consistency across formats covers holding it as work scales.
Identity holds when the rules and the work sit side by side while the work is being made. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
