Final answer:
To check if the input values are within the valid range (0 to 255), use an if statement in your code.
Step-by-step explanation:
In an RGB color value, each color component (red, green, and blue) is represented by a number ranging from 0 to 255. To check if the input values are within the valid range, you can use an if statement. Here's an example in Python:
red = int(input('Enter the red component: '))
green = int(input('Enter the green component: '))
blue = int(input('Enter the blue component: '))
if red < 0 or red > 255:
print('Red number is not correct.')
if green < 0 or green > 255:
print('Green number is not correct.')
if blue < 0 or blue > 255:
print('Blue number is not correct.')
