I posted in Facebook's Iris Lovers a couple of photos of my rebloomer, Starring Encore, which was taken in mid-November. At that time, Starring Encore's blossoms were a definite raspberry color. Even for the Phoenix area, the outside temperature was 8-10 degrees warmer than usual. In mid-December the blossoms were purple with hints of red. I asked folks on Facebook's Iris Lovers to explain why the color changed. Their strong consensus was the change in temperature. Two photos of the raspberry colored blossoms are from mid-Nov. The purple one is from mid-Dec. The colors in these photos were not edited with Photoshop.

I think lighting and sun vs shade makes a big difference too. The foliage in the last photo is a different colour too.

I have this gut feeling that rain levels and type of fertilizer used can influence colors as well.

I have a friend in the Phoenix area that I sent some irises to. When she sends me pictures of the blooms sometimes they are so different I can hardly recognize them. Others are more similar to the colors they are here. I'm sure it's due to the temperature differences.

My first photos of Haunted Heart were much deeper in color after the rain and cool days. Then, when it warmed up the blooms were much lighter.

You might also factor in the freshness of the flower, amount of sun or daylight hours, time of day, Humidity, and the type of camera, as all will affect your flowers and pictures. My phone camera "fabulizes" colors, making them much brighter. I take that into account if I'm wanting to show an accurate color of a flower. That said, 'Starring Encore' does change /fades for me as it ages... and is a bit deeper in it's fall bloom. I think temperature affects the brightness in that it doesn't fade, or age as quickly, and retains its just-opened look, or bud stage color longer. Some varieties change a lot as they age... certain varieties of Burseen's come to mind.

I think aging plays a big factor in the Haunted Heart pictures. Mine fades after opening.

While I agree that temps can change a iris' color, I think that shade versus sun and type of camera also are big influences. Type of soil and minerals within the soil do affect brightness, but that would not be a factor in the same iris.

An example of how lighting plays a factor can be shown in a few pictures I took of Burseen's Virtual Reality.

Early morning, just opened: Thumb of 2019-12-29/Lestv/3f1a58 In sun: Thumb of 2019-12-29/Lestv/b59980

In full shade: Thumb of 2019-12-29/Lestv/eab543

Shade makes it look like an entirely different iris, but it is a bud from the same stalk as the other 2 taken within a 3 day period. A bloom that opened a couple days later was a shade of color between the first one shown and the dark shade one. The dark shade one did have some frost damage and did stay a bit darker than the other blooms. So in this case you could say that both lighting and temperature affected it's color.
