I'm writing a 2D pixel art game in SFML and I want to add some simple mood lighting effects, such as a fluorescent lamp hanging overhead, or a glowing button on a computer console. Any thoughts on using OpenGL shaders vs. plain SFML/C++ code to do this?

I figure I could implement lighting well enough in SFML using overlaid textures and blend modes and my own pixel-crawling logic. Then I wouldn't have to worry about learning GLSL, graphics card compatibilities, avoiding "deprecated" features like gl_FragColor, etc. etc. Performance is probably not an issue since my game is visually simple.

But maybe someone with more experience knows reasons I should suck it up and use a proper shader. Any thoughts on these general approaches? Thanks for input.

No need to reinvent the wheel... Have a look at the Let There Be Light library 8)

Thanks for the link. Looks like that library uses shaders, so I'll take that as an implicit vote for "use shaders" (and maybe that library)
