These charts are intended as a guideline for custom orders, please be aware that "shades of" is always a better option than expecting an exact match*, as then you can't go wrong and it will add depth.
You are welcome to mention your specific colors required in custom order notes. Here is an example:
If you are looking for Lilac - Purple chart, Violet, No's 3, 4 and 5.
* colors may appear slightly different as devises vary.
