I searched a lot around the Internet but I can't figure out how to change the color of a texture.
I'm drawing a sun using the texture file (.sgi) my professor gave me, if I set the emission color of the sphere to white this is the color I obtain:

So far the only thing I managed to do is to set the emission color to red so the sun now is dark red, but is there something else I can do to make the Sun more yellow? The green component keeps coming out!

Here is the sun code:
Code :
	static GLfloat sunRed[]= {1.0, 0.0, 0.0, 1.0};
	static GLfloat white[] = {1.0,1.0,1.0,1.0};
	GLUquadric* a = gluNewQuadric();
	/* save attributes */
	glEnable(GL_TEXTURE_2D); /* enable 2D texture mapping */
		glTranslatef(500, 50, 0);
		glMaterialfv(GL_FRONT, GL_EMISSION, sunRed);
		glBindTexture(GL_TEXTURE_2D, g_textureArray[0]);
		gluQuadricTexture(a, GL_TRUE);
		gluSphere(a, 100, 24, 24);
	glDisable(GL_TEXTURE_2D); /* disable 2D texture mapping */
