Oh dear! You have my deepest sympathies for your loss. Take care of yourself, please, and don't fret about any of us online.
Do you have any clearer reference of lily or mind typing an explanation of the colors/design? I really have no idea what's going on colorwise since the ref you've provided is heavily shaded/has heavy lighting
Don't have any other references for her, but I don't mind describing? Just like Alistair, she's a solid, iridescent color all the way through- no patterns to her other than the shimmer of light reflecting off her scales. #670a4d and #a81647 are pretty much the base colors for her, though it's very common for her scales to take a more golden (#edc756) hue where the light hits them.
