I am currently working on a project where a website about Printing Services commissioned me to create drawings as graphics for one of their clients who wish to publish an art magazine. It was a pretty easy task until they told be that the illustrations must be in full color and rendered digitally. It means that the artworks are colored using a graphics software. They gave me a long time frame for the project that's why I am currently reviewing which software is best to use in terms of coloring.
Can I ask some suggestions from anyone? What is the best software to use? I am considering Corel Draw and Photoshop right now but I am still looking for other options. I'd be glad to hear some words from anyone.
Thanks!
