Blip on spawn location

I try to put a specific blip at spawn (ID: 267), but it does not appear on the map, there is a limit? I’m just interested in putting a blip of no importance at the spawn spot when you enter the server.

spawnpoint ‘mp_m_freemode_01’ { x = 237.756180, y = -406.086792, z = 47.924366, blipid = 267, blipcolor = 85 }

And another question as to how and where I can change colors to these circles https://i.gyazo.com/b1a6f6095b7def593e9ebf546842f55c.png
