I've made a simple plugin to style the WP default backend.


Plugin Name: Admin CSS
Description: Custom Admin style. Made by LOOT
Author: LOOT
Version: 1.2
Author URI: http://weareloot.com

function admin_theme() {
    wp_enqueue_style('admin_theme', plugins_url('adminstyle.css', __FILE__));

function topbarstyle() {
    wp_enqueue_style('topbarstyle', plugins_url('topbarstyle.css', __FILE__));
add_action('admin_enqueue_scripts', 'admin_theme');
add_action('login_enqueue_scripts', 'admin_theme');
add_action('admin_enqueue_scripts', 'topbarstyle');
add_action('wp_head', 'topbarstyle' );

Then I have a bunch of CSS files and some colours defined in the topbarstyle.css like this:

/* General Colours */
:root {
    --color1: #f5f5f5;
    --color2: #d8d7da;
    --color-accent: #2748f3;
    --color-dark: #23282d;

I'd want to implement a settings page where those colours can be modified. I'm a total newbie in PHP and I'm trying to find resources, but thought I'd ask this over here as well Thanks!

This should get you started. Once you're more confident in plugin design I recommend using plugin boiler-plates you can create for free here: https://wppb.me/ They'll look pretty scary at first but as you gain confidence and knowledge, you won't be able to live without them.

Note: this is me just typing, expect typos.

    function My_Cool_Menu() {
        $icon_url = plugin_dir_url(__FILE__) . 'images/MyMenuIcon.png';
        add_menu_page('My Cool Page Title', 'My Cool Menu Title', 'edit_posts', 
        'MyPluginSlug', 'My_Cool_Plugin_main_menu', $icon_url);

    function My_Cool_Plugin_main_menu() {
        //create your html admin menus, buttons and such in this file
        include_once( 'MyCoolAdminPage.php' );

add_action('admin_menu', 'My_Cool_Menu');

edit and be sure you learn all about nonces!
