If we closely look at TV remote, we find red, green, yellow and blue buttons.
But we rarely know that why they are used ??
The coloured buttons are originally designed to make navigation easier when using interactive TV features.
Instead of pressing multiple keys, viewers could quickly select options using these coloured shortcuts.
These colour coded buttons control on-screen menus and special functions.
The green button is commonly used for confirmation or quick access to certain features.
The yellow button is usually linked to extra option or tool. Like opening subtitles, showing additional program details or accessing additional editing options.
Blue button often provides advanced navigation options or shortcuts.
