Unit 2 Color: 5 of 23

By turning on one of the bulbs to a maximum, we can make the primary colors:

   
Red
RGB= (255,0,0)
Green
RGB= (0,255,0)
Blue
RGB= (0,0,255)

Just as with the grays, setting the three bulbs to different settings will produce different shades of the primary colors. How many different colors can we make? 

With 256 settings for each bulb, we have 256x256x256 = 16.7 million different colors we can make!. This palette -a grouping of colors-is known as True Color or 24 Bit Color since each bulb has 8 bits. Recall that 28 is 256. You will about more palettes later but now you will get to make some colors.
