Size and scale establish visual hierarchy because our eyes are drawn to larger elements first, signaling what to notice and in what order. By making the most important element the largest, it becomes the focal point, while medium-sized items support it and small ones recede, guiding the viewer through the composition in a deliberate sequence. In practice, a poster uses a bold, oversized headline to grab attention, a smaller subhead for context, and even smaller body text for details, creating a clear reading path through careful differences in size. Pairing this with thoughtful spacing and alignment reinforces the intended order and keeps the layout cohesive. While color, texture, and placement can influence interest, they don’t establish priority as reliably as size and scale; random placement, in particular, tends to disrupt any intended reading order.

Staying crisp when you resize comes from using a vector-based approach. Vector graphics describe each shape with mathematical equations that define paths and curves (for example, Bezier curves). When you scale, the image is recalculated from those equations, so edges stay clean and sharp at any size. Raster graphics and bitmap images, by contrast, are made of a fixed grid of pixels; enlarging them spreads those pixels, causing blur or jagged edges. Pixel art is a type of raster image built from a grid of colored squares, so scaling usually looks blocky. Because vector graphics are defined mathematically and resolution-independent, they remain crisp at any scale.

Subtractive color mixing is the idea here. In a subtractive system, pigments sit on a white surface, and each pigment absorbs (subtracts) certain wavelengths of light. White is the starting color because the surface reflects all wavelengths. When you add pigments, you subtract more and more light, moving toward darker tones. If you remove all color pigments, nothing is left to absorb light, so the surface remains white. That’s why this system is described as becoming white when all colors are removed. By contrast, additive color is about light itself—when you combine all colors of light, you get white, not when you remove them. The RGB model is the standard additive system used on screens. Analog color isn’t a formal mixing system in the same sense. So the described behavior fits subtractive color best.

The main idea here is how typefaces are grouped by the presence or absence of serifs. Sans serif means there are no serifs—the small decorative strokes at the ends of letters—and the strokes are typically uniform in width. This describes a clean, modern look that’s common in digital and contemporary design. The other descriptions refer to styles that do have serifs or distinct characteristics: serif typefaces (often called old style) have those small finishing strokes; script mimics handwriting with connected, flowing letters; and blackletter uses dense, angular shapes. Because sans serif specifically denotes no serifs and uniform strokes, it’s the best match for the given description.
