Assuming all the photos are correctly identified, including mine, here are some reasons why they might look different:
Age of bloom when photo was taken: I caught mine right after they opened when colors are most intense. Also no shiny glare from the sun as in other photos.
Resolution of photo and differences in cameras used: In my photo the tango speckling is resolved along the edges right out to the tips of the petals. Some photos won't show that.
Environmental conditions that vary with location can greatly affect coloration. I have received many comments, mainly from the Midwest (think HOT), about how much more colorful some of my lilies are than the same cultivar in their gardens. Temperature can greatly affect colors of many cultivars.
Here is a link to the similar lily Starburst. I no longer have it but I remember its flowers as being smaller than Olina's.
