You can apply a variety of color processing to your images.

Normalize brightness of an individual image for better color compatibility with other images to generate naturally looking maps. TOA reflectance with 10k scaling factor.

Note: Brightness can only be applied to RGB.

Examples of queries:

Basic correction of colors and brightness:  color=none 

http://{s}.sat.owm.io/sql/{z}/{x}/{y}?appid={APIKEY}&select=b4,b3,b2&from=s2&color=none


color=brightness>3000

http://{s}.sat.owm.io/sql/{z}/{x}/{y}?appid={APIKEY}&select=b4,b3,b2&from=s2&color=brightness>3000


Configure a color palette of any image to get proper colors, e.g. for vegetation indexes.

Note:  Palette can only be applied to vegetation indexes
