Based on your query for a typographic poster using Helvetica and Garamond, I’ve created a color palette that features high to medium contrast without the use of red. Here’s the suggested color palette:

json
{
  "palette_name": "Typographic Contrast",
  "colors": [
    {
      "name": "Charcoal",
      "hex_code": "
          
          #333333
       "
    },
    {
      "name": "Steel Blue",
      "hex_code": "
          
          #4682B4
       "
    },
    {
      "name": "Goldenrod",
      "hex_code": "
          
          #DAA520
       "
    }
  ]
}

Palette Description: This palette combines a deep charcoal gray for strong text contrasts with a soft steel blue for a calming effect, complemented by a warm goldenrod that adds a touch of brightness without overwhelming the design. Ideal for a typographic poster that needs to stand out while maintaining elegance.

Would you like any additional colors or adjustments to this palette?
