Memento Mori
For this group of paintings I observed, collected, and reproduced the colors of a fresh Meyer lemon over time.
From Wikipedia: Memento mori is the medieval Latin theory and practice of reflection on mortality, especially as a means of considering the vanity of earthly life and the transient nature of all earthly goods and pursuits. Memento mori has been an important part of ascetic disciplines as a means of perfecting the character, by cultivating detachment and other virtues, and turning the attention towards the immortality of the soul and the afterlife.
In art, memento mori are artistic or symbolic reminders of mortality.
