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.

BodyButter yellow

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

RoofCharcoal

Use smooth light strokes following the roof curve. Keep the window surround brighter than the painted or vinyl surface.

InteriorTan

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 and white

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

MotelCream and turquoise

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

The first GTX combined restrained brightwork with a black grille and an argent-silver rear panel. A specialist review records optional racing stripes rather than treating them as compulsory equipment. Its paint table includes Bright Red, White and Turbine Bronze. These names offer a useful period palette but the exact stripe and interior combination should still be checked against a specific car. The present evidence is secondary and does not replace the original order record.

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

Keep the grille dark and the rear panel argent silver. Racing stripes were optional; do not imply every GTX carried them.

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. Large custom bonnet scoop and contrasting bonnet treatment instead of standard GTX bonnet detailing.

In the coloured example

The pencil example uses butter yellow. 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 GTX’s formal roofline before adding strong colour. Work from a light first layer so that the panel boundaries remain clear.

02

Finish the paired bonnet scoops and lower bright trim with a sharp pencil. Preserve small white highlights so these details stay separate from the surrounding paint.

03

Keep the country motel parking area with a long low roof in quieter tones. A lighter background gives the car’s silhouette room to stand out.
