Welcome to the world of trees.
Trees have captivated me for as long as I can remember. Trees are among the oldest and most vital living things on Earth, silent giants that shape our landscapes, clean our air, shelter countless species, and mark the passing of seasons in ways nothing else quite can. Can anything be kinder than trees?
Yet for all their presence in our daily lives, most of us walk past them without a second glance. Can you tell an oak from an elm? A pine from a spruce? Do you know why some trees lose their leaves while others stay green all year or how a single tree can live for thousands of years?
This guide invites you to slow down and look closer. You'll explore trees by their shape, leaf type, bark, and habitat, learning to identify common species and understand what makes each one remarkable. Whether you are an artist, a painter, a curious wanderer, a budding naturalist, or someone who simply wants to know the name of the tree in their backyard, there's something here for you.
Your journey into the canopy begins here.
Beginner: Anatomy & Silhouette
Every tree species has a characteristic silhouette determined by its branching architecture. Before mixing a single color, a painter must be able to identify and reproduce a tree's silhouette from memory. Select a species below to study its structure.
Silhouette Type
Broad Spreading Crown
Branching Pattern
Alternate, wide angles (45–70°)
Painter's Note
Paint the crown as three stacked cloud masses, one lit from above, one mid-tone, one deep shadow below. The trunk shortens to almost nothing beneath the crown at distance.
Intermediate: Branch Logic & Growth
Branches are not random. They follow consistent mathematical relationships: angle, taper, and hierarchy that are the same across all deciduous species. Once internalized, these rules let you invent convincing trees from imagination alone. Adjust the sliders to see the rules in action.
Narrow angles (10–20°) produce tall columnar forms like Lombardy poplars. Wide angles (45–60°) create the broad spreading crowns of oaks and beeches.
Each child branch retains this percentage of its parent's length. Low values produce small, bushy trees. High values produce tall, open-structured trees with long reach.
Six Rules of Branch Architecture
Every believable painted tree obeys these principles, even when painted loosely and from memory.
Rule of Thirds
The trunk occupies roughly the bottom third of the total tree height. The crown fills the upper two-thirds. Violating this makes trees look stunted or top-heavy.
Taper
Each branch generation is proportionally narrower than its parent, roughly 60–70% of the parent width. A branch that does not taper reads as a pipe, not living wood.
Alternating vs Opposite
Oaks and elms alternate left-right branches as they ascend. Maples and ashes branch in opposite symmetrical pairs. This is species identity in a single rule.
Terminal Bud Lift
Branch tips always curve slightly upward toward light. Even the lowest drooping branches tip up at the end. This gives trees their feeling of living energy.
Negative Space
The sky holes within a crown define it as powerfully as the foliage. A crown with no gaps reads as a cut-out shape. Paint the sky through the tree, not around it.
Gravity Droop
Lower branches sag under their own weight and the weight of foliage. Upper branches are more vertical. Paint the angular difference between lower and upper scaffold branches.
Advanced: Light, Shadow & Painting Method
A tree crown is not painted leaf-by-leaf. It is painted as a collection of foliage masses each mass is a clump of leaves treated as a single unified shape, lit from one consistent direction. The painter's greatest skill is learning to see and paint these masses rather than individual leaves.
Think in Masses
The crown is three shapes: a light mass (top-lit), a mid-tone body, and a dark shadow mass (underside). Paint these three shapes, not individual leaves. The illusion of foliage emerges automatically.
The 20% Rule
Highlights should cover no more than 20% of the crown area. The moment you overdo the light mass, the tree flattens. Keep the dark masses dominant, they create the sense of volume and interior depth.
Cast Shadow
The cast shadow on the ground anchors the tree to the earth. Without it, trees appear to float. The shadow ellipse always falls opposite the light source and is slightly cooler in temperature than the bark color.
Painting Workflow
A structured sequence prevents common mistakes. Follow these six steps in order, resist jumping ahead to details before the masses are resolved.
Sky First
Lay in the full sky before touching the tree. The tree is painted into and over the sky, not behind it. This gives atmospheric depth to the silhouette edges.
Shadow Mass
Block the darkest foliage mass first, the underside and deep interior of the crown. This is your anchor. All lighter values must relate to this dark.
Mid-Tone Fill
Add the mid-tone green across the bulk of the crown. Work broadly. This is the “local color” of the tree, not its light or shadow, just its own hue.
Highlight Clusters
Apply the lightest green only on the upward-facing foliage surfaces. Keep it small, highlights should never cover more than 20% of the crown area.
Branch Breaks
Pull branches and sky back through the crown with negative painting. This is what separates a believable tree from a green blob. Work dark over light.
Edge Quality
Vary hard and soft edges around the silhouette, hard in light, soft in shadow. A single continuous hard edge kills the illusion of depth in the crown.
Foliage Color Palette
Four values cover every zone in a lit tree. Each can be mixed from a small set of standard pigments. Temperature shifts (warm highlights, cool shadows) create depth even before any texture is added.
