I need assistance in making a simple html and php script that lets a user explor the RGB color specturum. It should be able to use 6 buttons (R+,G+,B+,R-,G-,B-) that when pressed, add or subtract 2 points (ranging from 0-255) of that color from the RGB ratio. The new RGB color is then displayed in a small window/box at the bottom of the page for the user to see. This should allow the user to explore all the different colors by changing the amount of R(red), G(green), and B(blue) amounts. If theres anything I can do to help please let me know, thank you!

<?php
session_start();
if (!isset($_GET['action']))
{
    $_SESSION["R"] = 0;
    $_SESSION["G"] = 0;
    $_SESSION["B"] = 244;

}

function checkLimit(int $a)
{
    if ($a >= 0 && $a <= 255)
    {
        return True;
    }
    return False;
}
if (isset($_GET['action']))
{

    if ($_GET['action'] == 'R+')
    {
        if (checkLimit($_SESSION["R"] + 2))
        {
            $_SESSION["R"] = $_SESSION["R"] + 2;
        }

    }
    elseif ($_GET['action'] == 'G+')
    {
        if (checkLimit($_SESSION["G"] + 2))
        {
            $_SESSION["G"] = $_SESSION["G"] + 2;
        }

    }
    elseif ($_GET['action'] == 'B+')
    {

        {
            $_SESSION["B"] = $_SESSION["B"] + 2;
        }
    }
    elseif ($_GET['action'] == 'R-')
    {
        if (checkLimit($_SESSION["R"] - 2))

        }
    }
    else
    {

        {
            $_SESSION["B"] = $_SESSION["B"] - 2;

    }
