To detect colors in Scratch, you can use the “touching color” block or the “color sensing” block. Here's how you can do it: 1. Using the “touching color” block: - This block checks if a sprite is touching a specific color. - You can use it in conditional statements to trigger actions when the sprite touches a certain color.There are about 120 million of them in our eyes - compared to around 6 million cone cells, which are the cells that detect colour. So, in other words, our eyes have the potential to be highly sensitive to light, but they're usually so stimulated that we haven't really been able to test their limits.
