About the Theta Greek Letter Circle color filled icon
A tall narrow oval crossed by a single horizontal bar forms the Greek capital theta, centered inside a clean circular badge. The letter stands for angles in trigonometry, temperature and phase in physics, and a parameter in statistics, making it useful for math and engineering courseware, scientific calculators, equation editors, lab report templates, and fraternity or classical-themed branding.
The concentric composition contrasts the wide outer ring with the slimmer inner oval, and the crossbar sits exactly on the vertical midpoint for balance. It belongs with alpha, beta, pi, sigma and omega icons in the Greek alphabet set. Because the crossbar is thin, avoid using it below 24 px.
This is the colour filled version of the theta greek letter circle icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
