I''m not quite sure what you''re looking for but two good books to read about color and value are "Color for the Artist" by Wendon Blake and "Tonal Value" by Angela Gair. Both teach you the basics of each subject and both tell you how to use them to create better looking paintings.

there is something that every graphist should know, it''s one of the major theory of color

the seven color contrast
