snowStorm.snowColor = ‘#bbbbbb’; // changes the color of snow by changing the value of the Hexadecimal color. For example, change #bbbbbb(grayish) to #ff0000 to make it red. You can pick a color at ColorPicker.com.
snowStorm.flakesMaxActive = 30; controls the amount of snowflakes showing in the page at the same time. 30 means there would be at most 30 snowflakes falling. Don’t go crazy with this. Better leave it as it is or don’t make it more than 50.
