xcolor – Driver-independent color extensions for LaTeX and pdfLaTeX

The pack­age starts from the ba­sic fa­cil­i­ties of the color pack­age, and pro­vides easy driver-in­de­pen­dent ac­cess to sev­eral kinds of color tints, shades, tones, and mixes of ar­bi­trary col­ors. It al­lows a user to se­lect a doc­u­ment-wide tar­get color model and of­fers com­plete tools for con­ver­sion be­tween eight color mod­els. Ad­di­tion­ally, there is a com­mand for al­ter­nat­ing row col­ors plus re­peated non-aligned ma­te­rial (like hor­i­zon­tal lines) in ta­bles. Colors can be mixed like \color{red!30!green!40!blue}.
