Special Finishes

As a Reddick fan, these last few weeks have been exciting and expensive! I only preorder Reddick race wins and have never felt the urge to get a special finish. With the importance of the Daytona 500 win, I decided to get the RCCA membership to be able to get a special finish. I tried looking around but there weren’t many examples of some of the finishes. Specifically “flash color”, “galaxy color”, and “liquid color”. I landed on the flash color after asking ChatGPT for some type of guide. I still haven’t had luck in finding a comprehensive guide or side-by-side of the finishes on a 1/24 diecast. If you guys have special finishes, please post pics in the comments to help show the differences! It would be greatly appreciated!
