Grease Pencil in Eevee renders dark - Lighting and Rendering

In Blender 2.8, I created a cake model in eevee and used grease pencil to draw the icing. The issue I’m running into is that the grease pencil strokes are always very dark, even when I set the color to full white with maximum value. I even placed a lamp with a very high brightness next to the model to blow out all of the other materials, but the grease pencil is still this gray color despite being set to white. Does anyone know how to fix this?

Eevee render help? Render is way darker than Viewport shows. : r/blender
