How do I add color to the output of a custom completion?

[parnell]

I am trying to show some colors for the project names for a command I use frequently. I have the following code which works for the custom completions, but I can't figure out the colors. Using typical color codes doesn't work and I'm at a loss.

Any help/suggestions?

Thanks!

# Define the autocomplete function
_complete_projects() {
    # Ensure the environment variable is set
    if [[ -z "$P_ITERM_PROJECTS_DIR" ]]; then
        return 1
    fi

    # Use the find command to list all .sh project files and top-level directories
    local projects
    projects=$(find "$P_ITERM_PROJECTS_DIR" -maxdepth 1 \( -type f -name '*.sh' -o -type d \) ! -path "$P_ITERM_PROJECTS_DIR" -print 2>/dev/null)

    # Extract the project names from the full paths
    local project_names
    project_names=()
    for project in ${(f)projects}; do
        project_name="${project#$P_ITERM_PROJECTS_DIR/}"
        project_name="${project_name}"
        project_names+=("$project_name")
    done

    # Remove duplicates and prepare the completion list
    project_names=("${(@u)project_names}")

    # Provide the completion options
    _describe 'projects' project_names
}

# Bind the function to the restore_project command
compdef _complete_projects restore_project
