They are close to the Render colours, they weren't the greatest sample photos you can see much better ones here: https://sterlingcophotography.pixieset.com/hundredacrewoods/
Harsh!

EDIT: Lighting has a large impact on light coloured plastics, and the first sample photos where taken under a white light leading to them looking almost white.
Yep! We talk a lot about color matching in the IC, but I'll take a second to chat about it here, too.
What you see on a screen is always going to be an imperfect representation of the physical product - even with fully calibrated monitors, a lot of time spent tweaking colors, comparing with high CRI bulbs, etc., it's simply impossible to get a perfect match, and that's even staying within our fully calibrated setup. Throw in what everyone else sees, with monitors that might be uncalibrated, calibrated to a different gamma point, or even calibrated but with different coverage of sRGB, and things start to look even more different. Now if you throw in photos of real life things, and lighting has a huge impact on how colors appear, as does the camera itself. The sample photos were taken with a camera that has it's own color correction profiles calibrated to the lighting, and the shots were lit with high CRI lights, but it is quite bright.
All of that might sound like a lot of handwaving and making excuses as to why renders and reality never fully meet, but it is really just to explain why we rely on physical standards in the end, as well as hard data. We have RAL colors picked for everything. The renders were matched to it as best as possible, and the target for the samples was also for these colors. Once the samples arrived, they were examined with a spectrophotometer - basically a device that tells us the color composition of a material under controlled lighting situations - and compared against out physical RAL samples. We can use the details on the differences in color to help the factory tweak the color for future samples. The white, for example, is quite close - it's on the edge of what most humans can perceive - but we still are asking the factory to revise and get it closer. In this case, the caps are actually a shade darker than the white we're targeting, despite my sample photos making them look brighter than the renders show.
As the process continues we'll keep providing updates on the color matching, provide photos, and I'll provide the delta E (Objective measure of color difference between two colors.) for the final approved colors.
