I'm a newbie about GIS. I'm from Italy and I've got a *.tif file of my region. I've loaded it has raster but I have a question:

The dem has a gradient colour magenta. How change this colour to typical "blu-green-yellow-brow" of Greografic representation?

Thanks

The best plugin to use to do colour ramps on rasters is the 1-band raster color table v1.10 plugin. Found in the plugin installer under the same name.

what a idiot! I didn't know how install plugins. Now I've discovered. Forgive me! Thanks –  alex May 29 '12 at 10:07
    
I looked in plug-in installer (QGIS 1.8.x) and cannot find 1-band raster color table. I looked at official repository for plug-ins and do not see it. Has it been discontinuted in the year and a half since the answer above? –  Catlike Dec 15 '13 at 21:15

you can check out More Color Ramps for QGIS with Colorbrewer, here from user @underdark.

you can add your color code following xml file for qgis style manager..

If you want to use them, just import the following XML file into QGIS Style Manager:

these don't work for raster layers. Only vectors. –  Nathan W May 29 '12 at 9:33
    
ah! it doesn't work for rasters, so it's not useful for me. I'd like to change my tif...a raster file –  alex May 29 '12 at 9:47
    
oh sorry, i didnt consider for raster... –  Aragon May 29 '12 at 14:36
    
actually, you can use Colorbrewer ramps, but you have to do it via the Colorbrewer website and the 1-band color table plugin mentioned in Nathan W's answer. Export the color map from Colorbrewer using simple copy 'n paste, then in the plugin, choose the ColorBrewer palette, and paste in the dialog that comes up. –  rudivonstaden Nov 29 '12 at 8:31
    
This functionality should really be part of core QGIS, not hidden in a plugin... –  markusN Dec 15 '12 at 14:21
