pretty much the title.

More emissive objects, so darker ones, absorb light more. That doesn’t make them more conductive. However, lots of the heat from a fire is in the form of light, so that part of your question doesn’t quite add up.
There are three possible way to transfer heat:
• Conduction
• Convection
• Irradiation
Object of darker colours absorb more heat through irradiation, but their colour doesn’t influence their ability to absorb heat in other ways.
That said, a lot of the heat from a fire is dispersed through irradiation, so they do absorb it. Fire does not conduce heat, it irradiates it. A hot piece of metal conducts heat.
Light is a short waveform, when it hits an object and gets absorbed the waveform lengthens and this lengthening caused heat.
The color black absorbs every color of light. Or every possible waveform coming from the sun. Not including any infrared radiation that also causes heat and is kinda really important to this discussion. The suns radiation can cause the materials in our clothes to vibrate on a micro scale causing heat.
