in reply to Using module Imager, how to convert scalar-color value to hex/rgba color value?

Use the rgba method to get the individual values and printf to format them in hex:

printf "%02x%02x%02x%02x\n", $colors[0]->rgba;

To output the whole array:

printf "%02x%02x%02x%02x\n", $_->rgba for @colors;
