PBR Color Reference List & Color Calibration for PBR Materials guide - by Grzegorz Baran
IMPORTANT!!!!
Due to technical issues with Gumroad, I had to unpublish all my products on this 'Gumroad' account.
Everyone who purchased any of my products will keep full access to them, but any further purchase of them wont be possible anymore for new customers anymore.
For this exact reason, this product cannot be purchased here anymore.
But dont worry, as I made it avaliable on my new gumroad account:
https://gbaran.gumroad.com/l/rjthlk
Of course, as soon I am sure everything works fine there, every single existing customer is going to get 100% dicount code to this product on my second gumroad account as well as an appology 100% discount code for another of my products. After this happens, I am going to stop all future updates on this version of the product, and continue them there instead.
I am really sorry for any inconvnience, but what happened was out of my control.
Best regards,
Grzegorz Baran

This product contains full access to fully functional 'PBR Color Reference List' (in editable excell source version and small PDF file) with all potential future updates I plan to make to it.
The version number below is going to change every time this list receives a signifficant update.
'Version 5 - 287 substances' - updated 30/07/2023
Color Calibration for PBR Materials-by Grzegorz Baran - E-Book Version 15 : Last edited in August 2023
This list is a 'must have' for any game studio and material artist who creates materials and textures for CG art as it contains list of color and luminance values for over 250 common substances. Therefore this list can and should be used as a fully functional Color Reference for any 'Physically Based Rendering' system. All values shared were carefuly measured with color spectrometer device and converted into PBR sRGB (2.2) and linear values.
This product also contains a PDF guide: 'Color Calibration for PBR Materials' which I hope going to help everyone in better understanding of overal color calibration subject and how to use this list in practice.
By purchasing this product you are getting access to these files:
Color Calibration for PBR Materials-by Grzegorz Baran.pdf
- a guide about color calibration for PBR materials
RGB-Color_Reference_List-Full.pdf
- full PDF version of PBR Color Reference List with substance dumbnails included whic can be easily carried on your mobile device etc.
RGB-Color_Reference_List-SOURCE.xlsx
- a large editable source excel file made in 'MS Office 2019' format with all equations used for convertions included. With this file anyone can easily expand this list, reformat it, modfiy equations or simply zoom-in into material preview thumbnails if neeeded.
Please bear in mind that by purchasing this product you also help to co-fund the further developement of this list as there are still many different surfaces left to measure and share.
Thank you all for your support,

Disclaimer to PBR Color Reference List:
This list contains values which come from measurements and color we perceive isn’t just an albedo but is made of many other components like specular, glare, reflections, micro-shadows, subsurface scattering etc. This is why I also included reference images with the X-Rite Color Checker next to them so they can help in you judgement. So please use this list as a guide and reference rather then absolute answer to everything. And please don’t be afraid to question material's look as at the end what matters is always the full light response. Not to mention that I can simply be wrong about something as it’s a bit uncharted and much wider territory then it appears to be and I believe the reason why there are no so many reliable reference lists out there already.

I was informed by some folks that my approach for cross-polarisation isnt 100% correct.
It is because X-Rite Color Checker isn’t fully dielectric and some of metal components was used to make its patches, therefore it reacts to cross polarised light in a slightly different way then surrounding non-metal dielectric environment. In result I need to process a few more tests in this areas and update this part of the book (page 38 onward). When its done and book gets a proper update, this comment will disappear.
