Dominant Industry's take leans toward the latter: a purple-toned blue with enough saturation to hold its own as a genuine daily-writer, not just a soft accent colour.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDominant Industry Standard 106 Periwinkle Blue\u003c\/strong\u003e is a 25ml fountain pen ink from the \u003cstrong\u003eStandard Series\u003c\/strong\u003e, made in small batches at Dominant Industry's studio in Paju, South Korea.
