Paint a lemon cross-section with rind rings, uneven segments and local highlights, preserving both irregularity and the overall ellipse.

A lemon slice has three neighbouring layers with different textures: rind, white pith and flesh. Paint one tilted on a table using ellipses, uneven segments and selected translucent lights. Colour, edges and values create the effect without a glow filter.

## Set up a separate study

Use an approximately 1400×1600 px canvas with the slice slightly below centre and room for its shadow. Separate ring guides, rind, flesh and detail. Test broad pale-yellow paint and fine membrane marks, making light-value differences visible without enclosing everything in black.

Check that outer edge, inner pith and flesh share one tilt. Slight eccentricity is fine, conflicting axes are not. Save the three colour layers before segments. If the pale regions merge, compare them against the background before raising every yellow’s saturation.

## Give all three rings the same tilt

Draw a broad shallow ellipse for the outside, a smaller one for the pith and the flesh within. Align their axes while allowing slight thickness variations. Reveal a narrow rind side below so the subject reads as a cut slice rather than a flat circular symbol.

Use mid-yellow rind, warm off-white pith and pale-yellow flesh. The pith still receives light and shade, so avoid a pure-white ring. Separate the lit cut surface from the darker lower thickness. If it resembles a doughnut, narrow the pith and soften the outer outline.

## Open segments around an offset centre

Offset the segment centre slightly and draw seven to nine unequal wedges. Join their divisions into the pith without crossing the rind. Vary segment widths and the central gap, avoiding the mechanical regularity of a pie chart.

Use pale membranes slightly lighter than the flesh, varying their width rather than outlining them in brown. Establish three adjacent segments first. If they resemble triangular biscuits, soften corners and let selected boundaries blend into the flesh instead of enclosing every wedge.

## Radiate pulp texture within each segment

Add short pale-yellow strokes radiating outward within each segment, curving near the edge. Vary their lengths and leave quiet areas. Build several groups of slender forms rather than dense parallel lines, with each group following its part of the wedge.

Add subtle yellow-orange beside selected pulp forms, retaining pale yellow on the other side. Keep the contrast gentle rather than creating hard wood grain. Resolve one segment, extend the clearest detail to two or three foreground wedges, and simplify the remainder.

## Keep colour in the translucent areas

Reserve creamy pale-yellow areas in one or two lit segments, framed by slightly darker flesh. Concentrate them on the light side rather than copying identical shapes everywhere. Avoid lowering the whole slice’s opacity, which would weaken the distinctions between rind, pith and flesh.

Add two or three tiny pale reflections aligned with the pulp. Too many resemble icing sugar. If the flesh turns grey, compare it with a clean pale-yellow swatch and repair key light areas. Raising every yellow’s saturation can also turn the pith into an unnatural glowing ring.

## Finish the rind thickness and table shadow

Suggest the rough rind with a few irregular darker-yellow dots. Use a broken lower dark to indicate thickness and connect it locally to the table shadow. A muted grey-violet shadow can provide contrast, but keep it subdued so it does not compete with the flesh.

Check aligned ellipse axes, unequal segments and coloured light areas. If the slice is a flat icon, restore lower thickness and contact. If it resembles an orange, reduce excessive red and thick pith. In the next study, change only the tilt and rebuild the compressed rings and wedges.

## Review and plan the next study

At normal size, compare rind, pith and flesh; at small size, check slice thickness; close up, look for membrane lines accidentally crossing the rind. Leave some fibres omitted. Compare the clearest and simplest segments to ensure they belong to the same cross-section.

Retain a texture-free native version and export a PNG showing all three layers. Next, use a flatter viewing angle and rebuild ellipse and wedge compression before fibres. Do not merely squash the finished image; reconsider the centre, pith thickness and visible side to study the new view.
