Hello,
Make sure that the color terms (like “Olive” and “Green”) are consistently used across all your products.
Check under Products > Attributes > Colors and ensure there are no duplicates or similar names.
When creating variations, double-check that the correct color is selected for each variation on each product.
Navigate to Products > Attributes > Edit Color Attribute terms and make sure each color attribute has the correct color code assigned.
Best Regards,
