A high-definition image of this color wheel would be beneficial for designers and artists looking to study color theory and color harmony. The Gatf color wheel typically features a circular arrangement of colors, with primary, secondary, and tertiary colors, along with various shades and tints. It is often used to illustrate color schemes and to understand the color wheel's structure and the relationships between different hues.
