We’ve come a long way since the old days of boring advertisements and signs in only red or white or green colors. You go to any baseball or basketball or even football game and you’ll notice that the signs are equipped with all three colors, red, blue and green. With computer enhancements and amazing programming through digital signage services and design teams you will find that these signs are as amazing as huge television sets. They organize the color flashing with precision timing much like pixels on a computer monitor using the three light bulbs in each section. Their are thousands in some cases of these light bulbs on a billboard!
