I make these pictures using a calibrated monitor and they are printed by professional labs so that the colours in the prints you purchase should appear as I intend them to, but please bear in mind that they might differ from those on your screen.
Unless you are also using calibrated hardware you could be seeing somewhat different colours on your computer: people often run their monitors too bright, for instance, or with over-vivid colour saturation - while mobile phones and tablets rarely have colour-corrected displays.
