Conversion Table Interest

Hi,
I’m currently working on a software that can be used to get a mix ratio using two or more paints to match a target paint. The bi-product is that I get the best match for paints between different brands.
I don’t know if there would be any interest in here to have a web page to look up the best matching paint for a paint in your preferred paint brand?
Nerd stats:
I’m using both a pro colorimeter and a pro spectrophotometer to obtain data from dried completely opaque paint swatches.
I’m using CIE Delta 2000 to compare paints in CIE LAB.
I have the whole Army Painter, Instar, Citadel Foundation and Citadel 49xxx(the small hard plastic boltershell pot with flip-top lid and blue label with white text that was released 2003 that replaced the boltershell pots with screw-top and beige label with black text that was released in 1998)
I also have the complete Citadel Base paint range and an almost complete Citadel Layer range.
I many paint pots from Vallejo’s Game and Model range.
I also have incomplete range of the Citadel Classic range and 83xxx that was produced by HMG and the infamous Citadel 47xxx range mentioned above together with the 49xxx.
deltaE2000 is the distance between two colours that are compared to eachother, a value of 0 means that the compared colours are the same.

deltaE definition:
<1: Not Perceptible by human eyes.
1-2: Perceptible through close observation.
2-10: Perceptible at a glance.
11-49: Colors are more similar than opposite.
100: Colors are exact opposite.

Re: Conversion Table Interest

A little taste of Citadel 49xxx equivalents. (Citadel 49xxx, Army Painter, Citadel Base, Citadel Layer, Instar Vintage and Instar Paint are measured with a spectrophotometer at Illuminant: D65, Observer: 2deg)
The outer rectangle is the Citadel49xxx and the inner is the closest matched colour from the paint brand above the colour swatch.
Three attachments are obviously the maximum, so I can unfortunately not add comparison swatches for more than the three I added.

The DeltaE2000 values are obtained with the Pro Colorimeter or in the case of 49xxx vs. Army Painter and 49xxx vs. Citadel Base it's a spectrophotometer.
Values can differ when I get around to measure the reflectance values with the spectrophotometer.

Lower DeltaE2000 values are better. With a DeltaE2000 value around 1.0 between two paints, it’s extremely hard to see the difference between them even if you have the two paint swatches beside eachother.

Citadel49xxx was released in May of 2003, which means that all painting guides in White Dwarf from this date used the 49xxx until the next change which happened in ~2010.

The sRGB values are calculated from the reflectance values.

Re: Conversion Table Interest

That is fascinating.

I'd be really interested to see some analysis between the original HMG Citadel Colour and British Standard https://www.hmgpaint.com/PDF/resources/ ... -chart.pdf I'm pretty sure they just picked out a range of standard colours an renamed them for marketing purposes.

Re: Conversion Table Interest

I’m in the process of completing my Citadel Layer range and I will updating the comparison list when I have added the Layer paints I currently have measured with the spectrophotometer. I will buy the missing paints next week and finally update the list after that. Then I will concentrate at getting the whole Instar range measured with the spectrophotometer and update the list regarding the beat matches with Instar.

After that I will create a new thread for the Citadel Foundation range measured with the spectrophotometer and compare With AP, Citadel Base and Layer and Instar.

After that I will create a new thread with the Citadel 83xxx range, the large hexagon pots with the rubber flip lid, it’s incomplete but I will measure what I have.

After that the Citadel Classic range will get its own thread.

Kind Regards
Kalle

Re: Conversion Table Interest

Thanks Harry :-)

I will update the Citadel Layer closest matches when I get hold of the last 11 paints in that range.
There are 80 paints in the Layer range that are not metallics, which makes the comparison with this range time consuming.
The steps I go through to get the values for one paint:
1. Buy the paint, easy but a very costly step depending on brand. This applies for currently available piants.
2. Stir the paint and shake the paint thoroughly with an agitator in the Pro Shaker and manually.
3. Paint a swatch on thick cardboard, it takes about seven to ten layers of slightly diluted paint to be sure it’s opaque.
4. Let it dry for about 12-24hours.
5. Measure the paint with the spectrophotometer, 10 measurements.
6. Type the values ranging from 380nm to 730nm in my paint mixing software.
7. Run the program to get the closest match to the target paint.

For an oop paint step 1 becomes even more costly and time consuming, and depending on the state it is in, an additional step of reviving the paint needs to be conducted.

Re: Conversion Table Interest

Hi,

Army Painter, Citadel Base, Citadel Layer and Instar Vintage equivalents are complete.
Next up are the Instar Paint equivalents.
The Vallejo Game Color range will be added after the Instar Paint range.

Re: Conversion Table Interest

Thanks :-)
With my background it comes naturally ;-)
This as I mentioned in my first post is just a small part that is necessary for my hobby project sw that can blend paint to reach a target colour.

By the way I have produced 40 paint swatches for VGC, so am still missing ~45 counting the extra opaque also.

Kind Regards
Kalle
