As much as I like brown and orange, I felt that the old banner was a bit too bright-- I have had a couple of people tell me that the orange of the font was vibrant enough that it scrambled their vision somwhat.
The new banner is a detail from "Portrait of a Girl" by Juan de Flandes, c. 1496. There is some academic debate over the subject of the picture; some argue that it is a portrait of Catalina (Catherine of Aragon), and others believe it is a portrait of her younger sister, Juana.
The font is Tycho's Elegy by Pia Frauss. I can't say enough wonderful things about her fonts-- you really must see them for yourself. This one is based on Tycho Brahe's own handwriting, and although it is later than the period I study, I loved the simple elegance and readability of it.
