Question: What would you use to access the tertiary brand color in a theme's fields.json file?

• brandSettings.colors[2]
• brandSettings.TertiaryColor
• brandSettings.colors[3]
• brandSettings.tertiaryColor

Explanation

In fields.json, HubSpot lets brand colors be referenced through brand_settings tokens, including the brand_settings.colors array. HubSpot’s documentation shows array-based color access using zero-based indexing, where the first entry is colors[0] and additional colors continue from colors[1] onward. That means the third color in the sequence is accessed at index 2. This is why the correct token uses the array form rather than a camel-case tertiary property name. HubSpot Developers

Why the other options are incorrect

brandSettings.TertiaryColor is incorrect because HubSpot documents brand_settings with snake_case naming and does not define a TertiaryColor token. HubSpot Developers

brandSettings.colors[3] is incorrect because HubSpot’s array access is zero-indexed, so index 3 points to the fourth color, not the third. HubSpot Developers

brandSettings.tertiaryColor is incorrect because HubSpot does not document a tertiaryColor token for fields.json brand color inheritance. HubSpot Developers
