Can you give references to the colour and colour temperature statements?

<p>What color is the moonlight? And does it's color temperature change along the day/night like the sun?</p>
<p>By &quot;What color is the moonlight&quot; I need the hex code of the color, or it's color tempreture if it constant.</p>

#FFFFFF is a pretty good value to use.  It's certainly close enough to be realistic.  Naturally there is variation when the moon is low.  However moonlight (and particularly when the moon is low) is normally too dim for colour to be clearly seen in objects illuminated only by moonlight. And yes, you are overthinking this if you are creating an illumination engine for a game.

Perceived color is a rabbit hole. Hex codes are for displays and printers, I don't think they are used by people who do room lighting (correct me if I'm wrong). And of course at low illumination levels are color sense changes a lot. If possible, see if you can find a copy of [Billmeyer and Saltzman's Principles of Color Technology](https://onlinelibrary.wiley.com/doi/book/10.1002/9781119367314) in a library if possible. On the other hand, color temperature would certainly be possible.

What color is the moonlight? And does it's color temperature change along the day/night like the sun?

By "What color is the moonlight" I need the hex code of the color, or it's color tempreture if it constant.

The color of moonlight, as perceived by our eyes, is white. It *appears* to be a brilliant white during night and it may also look slightly orange near the horizon.

As regard to color temperature, the cooler a body is the warmer is the light and the hotter a body is the cooler is the light; which is why Antares or Betelgeuse appear redder and Sirius looks blue. The color temperature of moon is ~4000K to 4500K. This means that the moonlight should look 'yellow and warm'.

The moonlight is a little red as the reflectance of moon increases with increase in wavelength (i.e longer and redder wavelength).
