The advanced one takes in account your destination color space (printer, separation, screens) your dislplay's color space, and several options for managing a missing or embedded profile scenario. You can't use a system set like that for pre-press. Just for RGB images to be displayed in a PC screen, and you should not trust in that RGB source for color separations. The web design rendering is based in the RGB standard for monitors and screens (home ones, not expensive or precise ones) sRGB IEC61966-2.1
Software applications such as Photoshop and GIMP can manipulate RGB colors by adjusting the levels of red, green, and blue channels independently. Additionally, coding languages like JavaScript and Python have libraries that allow for programmatically manipulating RGB values. Finally, hardware devices like LED lights and monitors can also be programmed to manipulate RGB colors.
