Feel free to try differnt colors at ColorExplorer and see how RGB boxes change. You will notice that each box never goes over the number 255. You would never see anything going over 255 in either red, green or blue. But what happens if RGB box has 255 units of red, 255 units of blue and 255 units of green? Try it out.

ColorExplorer has two boxes, the spectrum rectangle and the value-saturation square.

The spectrum rectangle is respnsible for hues. Observe the box ‘H’ when you move the curser upward or downward the spectrum rectangle¬†. Now, move the curser inside value-saturation square and pay attention to box “H’. You will notice that when you move curser insde value-saturation square, ‘H’ box values do not change.

In both cases RGB values change. I’ll explain why later.

Consider each hue as a house with its specific address on the visible spectrum rectangle. The value-saturation square shows what you can find inside that house. More specifically, RGB, Value and Saturation. We’ll get to these later.

Hue at its purest¬†form is always located on the upper right corner of the value-saturation square. ‘H’ value will indicate the degree and RGB will show you the amounts of red, green and blue present at any location of the value-saturation square.

Games

1. Secret color at H = 60 degrees has (Remember, for now, S and V should always be at 100)

a. 200 red, 50 blue, 60 green

b. 255 red. 255 green

 

2. If R = 255, G = 0 and blue = 255 what will you see in HSV boxes?

a. H = 10, S = 100, V = 100

b. H = 240, S = 100, V = 100

c. H = 300, S = 100, V = 100

d, H = 60, S = 100, V = 100

c. 60 red, 200 gree, 255 blue

d. 90 red, 50 green, 60 blue

3.
