A traditional mid yellow This soft mid yellow takes its name from the staircase at Sudbury Hall, where renowned colourist John Fowler used this shade to such great effect. Sudbury Yellow is particularly responsive to changes in light, reading as cleaner and brighter in well lit rooms or softening in dimly lit spaces alongside a stronger contrast like New White.
