Can you change colors and fonts with Canva design automation?

The ability to change colors and fonts per variant is a key differentiator between design automation tools. Here's what each approach supports:

Canva Bulk Create:

• Text content: Yes
• Images: Yes
• Colors: No
• Fonts: No
• Background: No

Canva Connect API (Autofill):

• Text content: Yes
• Images: Yes
• Colors: No
• Fonts: No
• Background: No

Layerre:

• Text content: Yes
• Images: Yes
• Colors: Yes
• Fonts: Yes
• Background: Yes

Why color and font changes matter:

Brand variations: If you manage multiple brands or sub-brands, you can use one template and swap the color scheme per brand.

Seasonal campaigns: Change the template colors from summer blues to holiday reds without creating separate templates.

A/B testing: Test different color schemes for ad creatives without designing multiple versions manually.

Localization: Some markets prefer different visual treatments, warm vs. cool colors, different typography styles.

Dark/light mode: Generate both light and dark versions of the same design from one template.

How it works in Layerre:

json
{
  "overrides": [
    {
      "layer_id": "HEADLINE_TEXT_LAYER_UUID",
      "properties": { "text": "Summer Sale", "color": "#FF6B35" }
    },
    {
      "layer_id": "BACKGROUND_OR_SHAPE_LAYER_UUID",
      "properties": { "color": "#FFF4E6" }
    },
    {
      "layer_id": "CTA_TEXT_LAYER_UUID",
      "properties": { "text": "Shop Now" }
    },
    {
      "layer_id": "PRODUCT_IMAGE_LAYER_UUID",
      "properties": { "img_url": "https://example.com/product.png" }
    }
  ],
  "export_type": "png"
}

Each render can specify different colors, fonts, and content, all from the same base Canva template. This means fewer templates to maintain and more flexibility per variant.
