PPI stands for Point Per Inch. PPI is the number of dots per inch in a printer's resolution or the number of pixels per inch in a monitor's screen resolution. The more PPI, the higher your image quality will be as it becomes sharper and clearer. The lower your PPI, the lower your image quality will be, and the more likely you'll see individual pixels in an image.
Colours that directly across the colour wheel, like blue and orange. When you put these colours next to each other, they make a great contrast together. Complementary colours are often found in nature.
