[QGIS-Developer] PyQgis, How to get the list of colors by pixel values

[Xavier Corredor Llano]

Hello everyone,

For example, if you have loaded a integer raster image, this raster showed in 
Qgis with colors by pixel values (automatic or modified by user). How to get, 
by pixel value the correspondent color as is drawed in Qgis? I need the list 
of colors for all pixel values for specific layer (raster with only integer or 
byte data type without color table).

Thanks!
