Newsec graphics should be shaded with Newsec colors, using no reflection, pecular or bump effects. Do not use standard drop shadows. Radial gradient may be used to backgrounds to provide a vignette effect. However, reflection, specular, shadows and lightning may be used for environments as stated above.
Graphics, and in particular, colored plates are well suited to make transparent in order to add depth and visual interest to the scene. Use the Newsec color palette and lower the opacity parameter to introduce a subtle see-through effect. Remember that a little goes a long way.
