It is a mixture of both. A hotter star will generally appear brighter than a cooler star of the same size. Similarly, a large star will appear brighter than a small one of the same temperature. The brightest stars are generally red supergiants, which are comparatively cool stars, but are so large that their size more than makes up for it. A star's apparent brightness from any given vantage point also depends on its distance. The closer a star is to you, the brighter it will appear.
The brightest stars appear brighter because they are closer to Earth or intrinsically brighter due to their size, temperature, or luminosity compared to other stars. Their brightness makes them stand out more in the night sky.
A microscope uses lenses to magnify and illuminate objects to make them appear brighter and larger. By bending and focusing light, microscopes can reveal details that are not visible to the naked eye.
Luminous objects appear brighter in the dark because they emit light, which becomes more noticeable when there is less ambient light present. This contrast makes them appear to grow or shine more prominently in the dark.

Those stars are too far away for us to see them individually, but their combined light makes part of the night sky look brighter.

Copper, bronze, and brown eyeliners can enhance blue eyes by creating a contrast that makes them appear brighter. The warm tones in these shades complement the coolness of blue eyes, making them stand out.
During the fall season, leaves change color because the green chlorophyll in the leaves breaks down and reveals other pigments, such as reds, oranges, and yellows. This change in pigments makes the leaves appear brighter and more colorful.

The temperature of the star itself - and Earth's atmosphere.
They are complimentary colours - colours opposite each other in the colour wheel. This makes them appear brighter and look awesome. :)
How big, how hot (color/amount of energy emitted), how far, light pollution at viewing site
When there is little light like during night time, we can see the stars more clearly. This makes them look brighter and hence, larger.
Red blood cells (RBCs) contain a protein called hemoglobin, which binds to oxygen and gives them their red color. When RBCs are oxygenated, they appear brighter red, and when deoxygenated, they appear darker red. This is why blood in arteries, where oxygen is bound to hemoglobin, appears brighter red compared to blood in veins.
Luminous objects appear brighter in the dark because they emit light, which becomes more noticeable when there is less ambient light present. This contrast makes them appear to grow or shine more prominently in the dark.

Changing the amplitude of a light wave affects its brightness. A higher amplitude increases the intensity and makes the light appear brighter, while a lower amplitude decreases the intensity and makes the light appear dimmer. However, changing the amplitude does not affect the color or wavelength of the light wave.
