Standard tokens provide the look-and-feel of the Lightning Design
System in your custom components. You can override standard tokens to customize and apply
branding to your Lightning apps.
To override a standard token for your Lightning app, create a tokens bundle
with a unique name, for example
myOverrides. In the tokens resource,
redefine the value for a standard
token:
<aura:tokens>
<aura:token name="colorTextBrand" value="#8d7d74"/>
</aura:tokens>
In your Lightning app, specify the
tokens bundle in the
tokens
attribute:
<aura:application tokens="c:myOverrides">
<!-- Your app markup here -->
</aura:application>
Token overrides apply across your app, including resources and components provided by Salesforce and components of your own
that use tokens.
Packaging apps that use the tokens attribute is unsupported.
