# # Custom Theme Colors

Foxit PDF SDK for Web offers a public method `setThemeColor` that allows users to customize theme colors. Details are as follows:

    PDFViewCtrl.shared.setThemeColor([
            {
                dom: document.body, // Applied globally.
                colors: {
                    primary: "#409eff", // Optional. Sets the color for UI components like buttons and dropdowns.
                    background: "#999999", // Optional. Sets the background color for pages and input fields.
                    border: "", // Optional. Sets the border color. An empty string means using the default value.
                    link: "#9E3ABF", // Optional. Sets the color of links.
                    text: "#006ddd", // Optional. Sets the color of the text.
                },
            },
            {
                dom: document.getElementsByClassName("fv__ui-tab-nav")[0], // Applied to a specific DOM element.
                colors: {
                    text: "#d96f3f"
                },
            },
        ]);
