Hi,
I find interesting to follow his development of the Color Process since his
first patent (GB21958 of 1913 -or 1914?).
No, The process with the name "Color" process is only 1924, it is on my web site, it is easy to read this.
The other patents is for the 3 color layers, it is the same process of Sam Wang and Christina Z. Anderson but in 1908,it is 3 patents (+/- 10 pages), i am this patents in French but Alberto Novo find this for you without my help.
