Indicative finished example
01 / The palette

Colours used
in this example.

A practical palette for the indicative finished example. Build colour gradually and keep the small details clear.

Suggested pencil shades, not exact factory paint matches. Test colours on your paper before building richer layers.

BodyPale pistachio green

Build two or three light layers along the panels. Leave a narrow paper highlight beside the strongest body crease.

StripesBurnt orange and black

Establish the edges lightly before filling the centre. Follow their width through the car’s perspective.

InteriorSaddle tan

Keep the cabin slightly darker than the glass. Follow the seat divisions without filling every seam with black.

ChromeSilver

Keep the brightest strips white. Put a narrow cool grey band beside them to suggest reflected light.

TyresCharcoal

Layer charcoal gently around the sidewalls. Preserve lettering and any whitewall areas before deepening the rubber.

LampsCream and amber

Preserve a tiny white highlight on each lens. Keep coloured lenses distinct from the surrounding bright trim.

LandscapeAutumn gold and rust

Use light, open pencil strokes. Keep this area softer than the car and preserve clear edges around the mechanical detail.

BarnBrick red

Use light, open pencil strokes. Keep this area softer than the car and preserve clear edges around the mechanical detail.

03 / Colour references

Period finishes and details

A reproduced 1971 Pontiac ordering document lists Canyon Copper, Lucerne Blue and other finishes alongside the GTO Judge package. Those names provide stronger year-specific guidance than assuming the 1970 promotional palette continued unchanged. Specialist descriptions place the coloured stripes at the wing creases and identify 455 HO lettering. The precise body-to-stripe combination remains unchecked. Use one complete documented car as the final reference before assigning the three stripe colours.

Screen swatches are a colouring guide rather than exact paint matches.

Retain year-specific Judge identification and 455 HO lettering where supported by the reference car. Confirm the three-colour stripe pairing separately.

In the photographs

The photographs show individual cars in their present condition. Their paint, wheels and trim can reflect restoration or later choices. Use the dated finish references above when aiming for a period scheme. 1971 GTO; Judge specification is not documented by the source. These body references do not confirm the Judge package or its engine.

In the coloured example

The pencil example uses Pale pistachio green. It is a creative interpretation, not an exact paint-code match. Use the photographed trim for material cues while keeping the outlines and composition of your book page.

04 / Useful tips

Make the details count.

01

Plan the Judge’s extended Endura nose before adding strong colour. Work from a light first layer so that the panel boundaries remain clear.

02

Finish the wing graphics and spoiler edge with a sharp pencil. Preserve small white highlights so these details stay separate from the surrounding paint.

03

Keep the autumn country lane with a barn set far behind in quieter tones. A lighter background gives the car’s silhouette room to stand out.
