Original vs Blendmode vs Blendmode + Desaturate

No Photoshop. Pure CSS tint using mix-blend-mode. Add optional desaturation for a cooler, flatter look.

Image with brand tint using mix-blend-mode
Blendmode
.blend::after{
  content:"";
  position:absolute; inset:0;
  background:#2e75b6;   /* brand tint */
  mix-blend-mode: color;
  opacity:0.28;
}
Image with brand tint and desaturation
Blendmode + Desaturate
.blend-desat{
  filter: saturate(0.55); /* tone down saturation */
}
.blend-desat::after{
  content:"";
  position:absolute; inset:0;
  background:#2e75b6;
  mix-blend-mode: color;
  opacity:0.28;
}

Tweak: brand color, opacity, and saturate() to taste. Try mix-blend-mode: multiply for stronger results.
