Laravel 5.1 manyToMany with two classes and third in common - many-to-many

Question

Here is the example:
Two classes: chairs and tables. Both of those classes are connected with third class colours with ManyToMany relations.
Let's say I have element of chairs class with two colours: red and blue.
How do I get matching tables, the tables that also belong to red and blue?
EDIT:
Chair model:
class Chair extends Model
{
public function colours()
{
return $this->belongsToMany('App\Colour')->withTimestamps();
}
}
Table model:
class Table extends Model
{
public function colours()
{
return $this->belongsToMany('App\Colour')->withTimestamps();
}
}
Colors model:
class Colour extends Model
{
public function chairs()
{
return $this->belongsToMany('App\Chair')->withTimestamps();
}
public function tables()
{
return $this->belongsToMany('App\Tables')->withTimestamps();
}
}
Chair migration's up function:
public function up()
{
Schema::create('chairs', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->string('name');
});
}
Chair-Colour pivot table:
public function up()
{
Schema::create('chair_colour', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->integer('chair_id')->unsigned();
// $table->foreign('chair_id')->references('id')->on('chairs')->onDelete('cascade');
$table->integer('colour_id')->unsigned();
// $table->foreign('colour_id')->references('id')->on('colours')->onDelete('cascade');
});
}
Remaining migrations (tables, chair_table, colours) are the same.
Foreign key constrains are commented out because I had problems when refreshing migrations with them included.
This is just manyToMany relation but I hope it helps. I just made this up since my code is more complicated so if You see any typos feel free to correct them or notify me in comments.
Thank You!
