While the set-up process for Retina is similar to other themes, there are some additional settings to consider added in the latest versions of Retina (version 5+).
Select the variant style
Activate swatches by clicking Swatches below Variant style.
Identify swatch trigger
Use the Swatch trigger field to enter the variant label used for swatches.
Most often, the swatch trigger is "Color"—however, this could also apply to Pattern, Material, etc.
While the field is not case sensitive, it is important to match the spelling of the variant label (e.g. Color vs. Colour).
Adjust swatch size
Use the Swatch size slider to increase or decrease the swatch container size.
Select color option style
Select either Color swatch or Variant image from the Color option style dropdown.
Color swatch draws from a library of common colors to automatically assign colors to the variants with matching names. For example, if a variant is titled "Black" the theme will display the color associated with that color (hex code: #000000).
Variant image displays a condensed version of the image assigned to the variant. This option may be more suitable for patterns, gradients, or other swatch forms that need more than a solid color.
Fine-tune custom colors
If you're using the Color Swatch option, sometimes certain colors matched to variant titles are not accurate when compared to the product variant. Use the Custom colors field to identify and adjust colors to the desired hex code.
For example, if the product variant's Red is more of a Crimson, you could identify the color name "Red" by entering that in the field, then a colon (:) followed by the preferred hex code (#DC143C).
Repeat this for additional colors by adding a new line to the field with the same format.
