Smart colors are variable colors within your theme settings in Dock. This means that all presets and colors you select in Dock are not linked to a specific color, but rather to a category such as "Primary color." This implies that all elements linked to the "Primary color" will change when you modify the primary color once.
Additionally, you can determine your light and dark shades with smart colors. Some branding styles may not include pure black, opting for very dark gray or even very dark blue instead.
After incorporating this information, we can also combine these colors. For instance, you can set in your theme settings that you want only the light color to appear on the primary color. This way, you can add all your Blockbuilder presets in various color combinations within your branding to your website and have them change color schemes with minimal effort.
