Welcome to Pixelation! 

Be more specific.
Are you looking for a good commonly used palette?

Yes, That is what I mean for colors.

The most common problem new artists encounter is regards to saturation is using colors with too high of a saturation. When this happens, the colors start to burn the eyes. This can be a problem in any media, but because the colors in pixel art are made up of light, instead of pigment as in paint, the potential for colors being too bright or irritating is much higher. Notice how the colors in the second image are much easier on the eyes:


Luminescence (brightness):
Luminescence (also known as brightness or value) is how dark or light a color is. The higher the luminescence, the closer the color gets to white. If the luminescence is 0, then the color is black.
Here's a palette arranged as a luminescence scale for you visual learners:

low luminescence (darker colors) on the left, high luminescence (brighter colors) on the right
