Get post meta value array in serialized data - serialization

Question

I saved the information inside the database by Select-Option as serialized data.
this is my data in db :
a:2:{i:0;s:7:"#00CC6A";i:1;s:7:"#8E8CD8";}
when i want get posts with this query :
$the_query = new WP_Query(array(
'post_type' => 'product',
'showposts' => 5,
'meta_query' => array(
array(
'key' => '_my_color',
'value' => '#8E8CD8',
'compare' => 'LIKE'
)
)
));
This works . and i can get the post which value_meta is #8E8CD8
when i want to get post with array value , like this :
$the_query = new WP_Query(array(
'post_type' => 'product',
'showposts' => 5,
'meta_query' => array(
array(
'key' => '_my_color',
'value' => array('#8E8CD8','#00CC6A'),
'compare' => 'IN'
)
)
));
It doesn 't works .
i tried everything like :
serialize(array('#8E8CD8','#00CC6A'))
and this :
'relation' => 'OR',
array(
'key' => '_my_color',
'value' => '#8E8CD8',
'compare' => 'LIKE',
),
array(
'key' => '_my_color',
'value' => '#00CC6A',
'compare' => 'LIKE',
),array(
'key' => '_my_price_wd',
'value' => '585000',
'compare' => 'LIKE'
)
but i want AND result with _my_color_ and _my_price_wd_
i can't get relation with OR
