Entice the hummingbirds to your garden by planting something red, because this will entice them to stay and check out all your flowers, regardless of their color, in order to determine those that are good nectar sources.
You can also put red or orange surveyors tape or ribbons on your hummingbird feeders as another way to attract hummingbirds to your yard in the spring.
The idea is to entire the hummingbirds to visit your yard frequently and to make them want to stay for a while. The color red with help you do this but it is not the most important thing to keep in mind. Whenever choosing a flower, the hummingbird will select the flower with the highest nectar output and the richest concentration of sugars, regardless of the shape or color of the flower. Also more important than the color of the flower is how the nectar taste.
