Okay, so when we talk about a monochromatic image, we mean a picture that only uses one color. That's right, just one! Just like when you color with only one crayon.
But how can a picture only have one color and still show different things? Well, the picture might be made up of different shades and tones of that one color. Kind of like how a song can be made up of different notes and rhythms, even though it's all just music.
So when you look at a monochromatic image, you might see light areas, dark areas, and some areas in-between. These different shades and tones help make the picture interesting and show different things. It's kind of like how you can make different shapes with play dough just by using your hands to push and pull it into different shapes.
And did you know that black and white pictures are actually a type of monochromatic image? That's right! They might only use shades of gray, but it's still just one color.
So the next time you see a monochromatic image, think about how it only uses one color but still manages to show so much!
