Estoy intentando recrear una imagen en Ti.kZ. Lo que está debajo a la izquierda es el original, y lo que está debajo a la derecha es mi trabajo hasta ahora.
Aquí hay un MWE que generará mi resultado actual:

\pgfdeclareverticalshading{rainbow}{2cm}{color(0mm)=(red); color(4mm)=(orange); color(7mm)=(yellow); color(8mm)=(yellow); color(11mm)=(green); color(14mm)=(blue!50); color(15mm)=(blue!50); color(20mm)=(purple)}

Como puede ver, he conseguido casi todo lo suficientemente cerca para mi gusto. Sin embargo, no puedo entender cómo crear el sombreado del arco iris que se abre hacia afuera suavemente. Para repetir, puedo hacer el sombreado del arco iris linealmente \pgfdeclareverticalshadingcomo se muestra, pero no sé cómo crear la región de transición trapezoidal desde el sombreado aplastado etiquetado como "visible" hasta el sombreado más largo con números a su izquierda. Sé que es una cosa pequeña, pero tengo curiosidad porque he buscado mucho en este sitio web y en el Manual de PGF y no he podido resolverlo :)
Déjame saber si puedo aportar algo más, ¡gracias!

Usando un pequeño truco.
