%%%In material nodes for blender internal renderer the overall color of textures in Texture nodes is too bright. Maybe a wrong color space is used.

In the attached blend, the top plane called Nodes has a shader with nodes attached to it, the texture feeds into the color (diffuse) input of the materal.
The plane below called noNodes has a shader with the same texture assigned to the diffuse channel through the normal material textures.

Both materials are shadeless and should look the same.
The color of the texture node is much brighter than outside of the node editor both inside the node view and on the output.%%%

%%%The same issue is already in older Blender versions too (tried 2.61). Texture nodes are not color managed (since its implementation). If you disable color management things are the same.
Unfortunately the developer of texture nodes stopped maintaining it ages ago. It's something we wanted to remove for long already. No further work will be done here. Fixing this will also break every old file using texture nodes...%%%

%%%I mean the input type node "Texture" used in the material nodes, not the texture node system.%%%

%%%here is a screenshot, left the material node, right the image editor.
it looks to me like color correction is applied twice making the node output overbright

%%%My bad, when I saw "Texture nodes" it triggered already an aversion here :)

Doesn't take away that this error was also there in 2.61. I need to look into it with sergey.%%%

%%%Whenever I try to use a 16bit TIFF file rendered in Blender and saved to disk, loading it in an image input node in the compositor for further post-processing, the image appears very bright. It's quite like the example posted by Tobias above. Switching Colour Management on or off makes no difference. I wonder if this issue is related to the issue in this bug report, perhaps they can be fixed together.%%%
