Visible forms (Skt. rūpa; T. gzugs གཟུགས་; C. se; J. shiki; K. saek 色) are a subset of the skandha of rūpa (forms) that bear the same name as the skandha (i.e. rūpa).
Visible forms are characterized by shape and color.
Visible forms are identified as:
- one of the five sense objects
- one of the six sense objects
- one of the eighteen dhatus
- one of the twelve ayatanas
- belonging to rupa skandha (the aggregate of forms)
The Khenjuk states:
- Visible forms are the sense objects of the eye. They can be divided into two types: color-forms and shape-forms.
- Concerning the first [color-form], the four primary colors are blue, yellow, white, and red. The secondary colors are cloudy and smoky, dusty and misty, sunny and shady, light and dark.
- Spatial [form] is a visible form, for example, pure, clear space, free from something tangible that impedes other things. Reflections and so forth belong to this type.
- Perceptible [forms] such as the act of prostrating and the uniformly colored blue sky are also said to be included under visible forms.
- Many different secondary colors come about by mixing the primary colors.
- Shape-forms are, in general, said to be long or short, square or round, concave or convex, fine or gross, even or uneven. There are many subdivisions such as triangular, crescent-shaped, oblong, and so forth.
- These shapes and colors can be classed as attractive, repulsive, or neutral.
