Colder stars emit red light. Hot stars emit large amounts of green light with small amount of red and blue light, which balances out to a white color in human eyes.

How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
How do you choose an evaporative cooler?
To choose an evaporative cooler, determine the size of the cooler needed, the services of the evaporative cooler, and the correct type of cooler. Consider the accessories required and compare it with a traditional air conditioner.

How are temperature and color in stars linked?
The hotter they are, the bluer they are, the cooler they are, the redder they are.
What contains mostly older stars with red color?
Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
Which is cooler the blue stars or the red stars?
Red stars are cooler than blue stars
What galaxy contains mostly older stars with red color?
Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
What indicates stars of brightness and temperature?
The color of stars determines temperature. Red/brown stars are cooler, blue stars are hotter, and yellow stars are in between. Brightness also has some correlation with color. Both are based on many varying factors however.
Is there a correlation between star temperature and color?
Hot stars are usually white or blue, while cooler stars are either yellow or red.
What kind of stars are cooler then the sun?
red stars are cooler than the sun
What color are small cool stars?
The large hot stars are typically called "blue-white" stars or also Blue Giants. Cooler large stars are called Red Giants.
Are blue stars hotter or cooler than red stars?
According to Wien's law, red stars are cooler than blue stars. This concept can be easier to understand using a light bulb. For example, when you turn off a light, the temperature of the bulb will decrease and you will notice the bulb turning red. The cooler light becomes, you will notice the obvious change in brightness and the color shifts towards red and the intensity is lowered.
What is the relationship between the color and the temperature of star?
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".
