Hello everybody.

I am a Spanish (from Spain, Europe) professional PC programmer and graphic designer.

I started my career in 1988, and since then I participated in projects ranging from Z80 videogames to press agencies information management systems, and many, many more.

I love physics, astronomy and computers, but I like to know about everything.

My first contribution to the Wikipedia as a member were improvements to the List of palettes article. Over the months, I did some minor changes to some few articles and I pushed some comments in various discussion and talk pages, before I became a member.

Although my mother tongue is Spanish, by now I contribute mostly in the English Wikipedia.

Main contributions
Basically, more or less deeply rewritten articles.


 * RGB color model
 * List of palettes (and descendeants).
 * Palette (computing)
 * Indexed color
 * Grayscale
 * Gamma correction
 * Code page 437

And a miriad of extensions, corrections, etc. in many other related articles. Also, I contribute with images, basicaly to illustrate some computer graphics topics.
