When complete VI palettes are used inconsistently, define roles, combinations and selection rules. Color values state what a color is, not when to use it. Connect brand colors, backgrounds, text and emphasis to real materials so producers do not guess.

## Find Conflicts in Actual Use

Collect websites, briefs and common materials and mark colors, roles and producers. Check different colors serving one role or one color conveying conflicting meanings in similar contexts.

Do not count color codes alone. Different media can use different treatments with explained mappings. Conversely, identical values with unreadable text or confused priorities still fail application standards.

Success means specific conflicts and contexts identified, with business and design staff explaining necessary differences versus historic temporary choices.

## Define Roles and Combinations

Use real needs such as brand identification, main backgrounds, body text, secondary text and emphasis. Check webpage interaction states separately; brand colors need not express every button, error and prompt. Connect VI and interface rules. See [How to Choose Brand Colors That Work](https://www.jvds.cn/en/share/brand-design/brand-color-selection) for related checks.

For each role, state objects, allowed combinations, examples and unresolved cases. Flexible use is too vague, while unused media need no piles of rules. Cover daily production problems first.

When discussing branding and websites with [JVDS Design Studio](https://www.jvds.cn/en), provide materials and roles to apply VI to interfaces. Print, digital applications, fonts and ongoing maintenance follow scope.

## Test Choices with Real Content

Add real headings, text, images and marks. Check text-background distinction, priorities overwhelmed by emphasis and image conflicts with color blocks. Choices should serve reader tasks, not only empty samples.

If every product category uses the strongest main color, priorities may become indistinguishable. Assess separate roles for categories and branding through actual content instead of simply adding colors.

Check target conditions across media. Screen previews and final production can differ; relevant producers should verify final output rather than one monitor confirming everything. Necessary adjustments need approved mapping rules.

## Define Exceptions and Valid Versions

For new contexts beyond rules, explain tasks, conflicts and proposals to designated approvers. Retain reasons and scope and assess guideline updates. Each exception should not automatically create new brand colors.

Application files need current versions and access methods. Rework old materials according to identity impacts, content validity and use plans; palette updates do not instantly invalidate every asset.

Success means independent everyday color choices, clear exception paths and evidence-based review. The manual becomes usable rules rather than color blocks only designers can explain.

## Frequently Asked Questions

### Must the Main Brand Color Be Used for Every Primary Button?

Not automatically. Check tasks, readability and state distinctions and connect branding to functions. Actual conditions determine button rules.

### Do Slight Departmental Color Differences Require Rebuilding Everything?

Check sources and impact first. Media may need mappings. Revise arbitrary unapproved choices under current rules and use plans rather than invalidating all assets solely from code differences.
