Service Diagram Opens the Housing

Five colors, endless possibilities. Select a color to copy its HEX.

An industrial all-season palette of dark olive brass, technical cyan, two light neutrals, and a vivid violet fastener for a repairable lighting-parts catalog.

The feeling

A slotted cyan panel, numbered module, exposed violet fastener, and labeled service diagram organize an imagined repairable lamp housing

The mood

An exposed screw head begins the reading path across an olive-brass housing. Service Cyan forms the slotted panel, and Assembly White keeps the numbered replacement module and diagram labels crisp against the darker parts.

Module Label creates a pale identification plate, while Fastener Violet isolates the removable fixing point. Clean rules, numbered parts, and separated components show how the imagined lamp comes apart without making claims about materials, certification, or environmental performance.

How to use it

Use Workshop Olive for the catalog background with Assembly White for headings, part numbers, and service notes. Build the main service panel in Service Cyan and keep Assembly White for its labels.

Treat Module Label as a pale plate with Workshop Olive text, not Assembly White. Reserve Fastener Violet for the exposed screw head or a compact component tab, using Assembly White if it carries words. The 57/30/13 ratio means 57% Workshop Olive background, 30% Service Cyan primary panel, and 13% Module Label highlight; violet remains a small accent outside the surface split.

What to watch

Assembly White reaches 11.13:1 on Workshop Olive, 5.35:1 on Service Cyan, and 6.53:1 on Fastener Violet. It reaches only 1.27:1 on Module Label, so that pairing fails normal- and large-text AA. Use Workshop Olive on Module Label instead at 8.75:1.

Keep every label on the original solid, full-opacity HEX color used for its verified pairing. Write part names and states beside numbers and color marks, because color alone does not explain assembly or service status.

A considered balance

Make room for
the right colors.

Use Workshop Olive as the catalog field with Assembly White text. Build the main service panel in Service Cyan with Assembly White labels. Set the pale Module Label plate with Workshop Olive text. Keep Fastener Violet to a screw head or compact tab with Assembly White. Preserve the original full-opacity HEX colors and a 57/30/13 background-primary-highlight surface ratio.

Start with a generous background, introduce your primary color, then use the highlight sparingly. The ratios are a guide for large surfaces, not a fixed recipe.

Text on background

Text on primary
5.35:1 #F0F0EC on #256B74 · AA normal text
Text on highlight
1.27:1 #F0F0EC on #D4D7D2 · Not suitable for text

The original text has low contrast (1.27:1). This example uses Workshop Olive (#3B3213) from the same palette instead of #F0F0EC on #D4D7D2, improving contrast to 8.75:1. This meets WCAG AA for normal text.

Text on accent
6.53:1 #F0F0EC on #8129A8 · AA normal text

Contrast is calculated for these specific pairs. Large text means at least 24 px regular or about 18.7 px bold. Check every pairing in your final design.

COLOR NOTE

Assembly White fails normal- and large-text AA on Module Label at 1.27:1. Use Workshop Olive there at 8.75:1. Do not use color alone to identify a part or service state.

Mood: A slotted cyan panel, numbered module, exposed violet fastener, and labeled service diagram organize an imagined repairable lamp housing
Suggested uses: Sustainable brands
Application note: Use Workshop Olive as the catalog field with Assembly White text. Build the main service panel in Service Cyan with Assembly White labels. Set the pale Module Label plate with Workshop Olive text. Keep Fastener Violet to a screw head or compact tab with Assembly White. Preserve the original full-opacity HEX colors and a 57/30/13 background-primary-highlight surface ratio.
Avoid: Assembly White fails normal- and large-text AA on Module Label at 1.27:1. Use Workshop Olive there at 8.75:1. Do not use color alone to identify a part or service state.
Use approximately 57% background, 30% primary, and 13% highlight across large surfaces. These ratios are a starting point, not a rigid rule. Use text and accent colors according to their roles.

Keep the original HEX values. Choose readable text/background pairings without silently changing the palette. Do not introduce unrelated colors.

Background is the canvas, text is readable copy, primary is a key surface, highlight draws attention, and accent adds small secondary details.

Text/background contrast: 11.13:1. This is one measured pair, not a guarantee for the whole palette. Check every actual text/background pairing against WCAG AA. Prefer readable combinations from the original colors, keep visible keyboard focus, and never communicate state through color alone. If no original pairing meets the requirement, propose a separately labeled derived color with its original HEX, proposed HEX, purpose and measured contrast. Never overwrite the source palette.

This guide preserves the original HEX values. Review the output before using it.
