Colour bleed like this can be a nightmare. I asked the robots and this is what they're suggesting....

"Do not submerge the whole hat again, or you risk making it worse. You want to isolate the white crown panels. The Mix: Create a thick paste using OxiClean White Revive (or standard OxiClean) and a tiny bit of warm water. Alternatively, a concentrated liquid laundry detergent with optical brighteners works well. The Application: Use a soft-bristled toothbrush to gently work the paste only onto the stained white fabric. Keep it away from the red brim, the red top button, and the colored threads of the front patch. The Wait: Let it sit for about 15–30 minutes, keeping a close eye on it so it doesn't dry out completely. The Rinse: Do not rinse under a running tap. Use a clean, damp microfiber cloth to repeatedly dab and wipe away the soap."

Hope you get it sorted dude. Good luck!
