Laravel 5.1 ReflectionException Class does not exist [duplicate]

This question already has an answer here:

• Laravel 5 - artisan seed [ReflectionException] Class SongsTableSeeder does not exist 5 answers

We are working in team on a laravel project and I've pulled in my teammates work and when I try to run

"php artisan migrate:refresh --seed"

I get this weird error:

[ReflectionException] 
Class ColorsTableSeeder does not exist

The file ColorsTableSeeder does exist so I have no idea why I get this error ColorsTableSeeder:

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class ColorsTableSeeder extends Seeder
  {
    public function run()
    {
      DB::table('colors')->delete();
      $colorPalette = array('#000000','#663300', '#424153', '#999999', '#996633'); 
      $faker = Faker\Factory::create();
      $projects = App\Project::all(); //10

      foreach ($projects as $project)
      {
        foreach (range(1, 3) as $index) 
        {
            $project_id = $project['id'];
            DB::table('colors')->insert([
            'project_id' => $project_id,
            'color' => $faker->unique()->randomElement($colorPalette),
            ]);
        }
      // Reset
      $faker->unique(true);
      }
  }
}
