On Presentation
Sometimes a painting is not presented in the way the painter intended. Frame, wall colour, ambient light, and neighbouring works can alter chromatic relationships — what reads as luminous against a dark ground can flatten on white. El Greco's dynamic and unconventional use of colour (cool blues, hot crimsons, spiky greens) can behave entirely differently across different backgrounds.
Use the widget to the left to change the field on which the painting sits. Click any palette swatch or colour index entry to apply that pigment directly as the ground.
