Color Picker in Illustrator CC won't save small color changes for my object
I have a number of designs that I maintain in Illustrator covering the last five or so years. I am currently running Illustrator CC version 21.1.0 (64-bit) under Windows 10. I use the layers window to select an object and then double click the fill tool which opens the color picker dialog box. In the past I have been able to type in a color such as 915ca6, click OK and the color would change to the that fill color. This way I can use the same color fill across all my documents. However, in one of my designs I had the wrong color 925ca6. When I tried to change it to 915ca6 in the color picker and then click OK, it would not save the new color. I found that if I changed the color to something completely different by dragging to a new color and clicking OK it would save the new color, then if I went back and changed it to the color I actually wanted 915ca6 and clicked OK it would seem to save it properly. However, after saving, closing and reopening the document, the color would revert back to 925ca6 which is not the same color that is in my other documents. Why won't Illustrator save the new color properly? Does anyone know a work around for this problem?
Thanks
