view auction (affiliate button)

Hi’
does anyone know how a can change the text on the “view auction” (affiliate button) i only have UK Free p&p BIN items and “view auction” is misleading, i want to change it to “view item”

i would also like to change the colour of the header block from brown to orange, so if anyone could help me i would appreciate it 🙂
