Do LED smart lights emit blue light even when the visible light is red (or any other color)?

Look at this spectrum:

These LED smart light emit color by mixing Red, Green, and Blue (RGB) lights

If the only visible color is Red then, no, it doesn’t emit blue light

But if you select a color like yellow, for example, there will be an emit of blue light

The same goes for your monitor, it constantly emits blue light and has PWM flicker which is really harmful to your eyes
