I'm pretty sure that it's not possible. Instead you should use HTML-style labels, that are a more developped form of record nodes. You can define your node using the

tag, and set the color using bgcolor="your_color". A list of available colors is available here: http://www.graphviz.org/doc/info/colors.html (you also have a RGBA way of doing it, as described here: http://www.graphviz.org/doc/info/attrs.html#k:color)

With HTML labels, your example becomes as follows:

digraph G
{
    rankdir = LR;
    node1
    [
        shape = none
        label = <

corpus_language

id: en

name: Englist

sentence_count: 1027686

> ] node2 [ shape = none label = <

corpus_sentence

id: 1241798

text: Baseball is a sport

language_id: en

activity_id: 11

score: 124

> ] node1:port2 -> node2:port6 [label="language_id"] }

Here is the result:
