* Clouds are constantly changing: Clouds form, grow, dissipate, and change color all the time. There's no fixed number of white clouds at any given moment.
* Color is subjective: What one person sees as white, another might see as light gray or off-white.
* There are many types of clouds: Clouds can be white, gray, dark gray, or even have shades of pink, orange, or red depending on the time of day and the conditions.
So, while we can say that many clouds appear white, we can't put an exact number on it.
