Proton Quark Composition Diagram - Up and Down Quarks Explained #1747470 (License: Personal Use)

This diagram illustrates the quark composition of a proton, consisting of two down quarks (colored red and blue) and one up quark (green), each labeled with its respective flavor symbol. The spheres use color-coding to distinguish quark types and emphasize their arrangement in the standard model of particle physics. The clean, minimalist design aids educational clarity for students and science communicators.

Used in physics education websites, STEM blogs, and introductory particle physics pages to explain baryon structure; matches user intent for understanding atomic nuclei fundamentals or preparing classroom materials.
