A robust palette can transform a stock theme into a highly-personalized web presence that better reflects an organization’s brand. This talk will introduce theme developers to a palette system/method with these goals: apply a default color palette; use the Theme Customization API (i.e. Theme Customizer) to set theme-level colors; apply the customization options to the block editor swatches and ACF color picker; set the appropriate CSS properties to use the colors throughout the theme. As time allows, other palette systems will be discussed (e.g. Bootstrap Colors; Material Design Color System).
