## Foundations of Visual Design

### Elements of Design
Every visual work is built from fundamental elements:

**Line**: The most basic element — a point in motion. Lines create edges, define shapes, direct the eye, and convey emotion. Horizontal lines suggest calm and stability. Vertical lines suggest strength and aspiration. Diagonal lines create dynamism and tension. Curved lines imply organic movement and grace. Line wt (thickness) creates hier — heavier lines draw attention first.

**Shape**: Enclosed areas defined by line, col, or val cont. Geometric shapes (circles, squares, triangles) feel structured and intentional. Organic shapes (irregular, flowing) feel natural and approachable. Triangles are the most dynamic geometric shape — they imply direction and instability. Circles suggest unity and infinity. Squares suggest stability and order.

**Form**: Three-dimensional shape — sphere, cube, cone, cylinder. In 2D design, form is implied through shading, perspective, and overlapping. Understanding how light falls on basic forms (highlight, midtone, core shadow, reflected light, cast shadow) is the foundation of realistic rendering.

**Value**: The lightness or darkness of a tone, independent of col. val is MORE important than col for creating readable images — a design that works in grayscale will work in col, but not vice versa. High val cont creates drama and clarity. Low val cont creates subtlety and atmosphere. Squint at any image to see its val structure with col information reduced.

**Color**: See dedicated section below.

**Texture**: Surface quality — actual (tactile) or implied (visual). Texture adds richness and realism. In digital design, texture prevents the "flat and lifeless" problem. Subtle paper textures, grain, or material surfaces create depth and character without clutter.

**Space**: The area within and around elements. neg (empty space) is not wasted space — it provides breathing room, focuses attention, and creates elegance. Crowded designs feel chaotic; generous neg feels sophisticated. The ratio of positive to neg fundamentally controls how a design feels.
