[SDL,OpenGL,C#] Textures changing basic colours.

[Phill64]

Hi all,

First time I've fully gotten into OpenGL, I'm using C# 2.0 and utilising SDL.NET, though for now I think pictures are more important than the code.

Basically I've setup some controls and structs and got my app to be able to draw solid colour squares or textured squares to the screen. Here's the weird part, If I load one of my images "image.jpg" it looks fine... but if I load my other "test.jpg" the solid red square is darkened and I don't know why.

I'm hoping an OpenGL vet knows exactly what causes this and it's a simple fix

(NOTE: The attached image is of 2 different instances not 1, I just pasted them together is all)
