I am unable to reset the browser visualization styles to the default grey colored nodes and relationships using :style reset in the browser. It seems to be setting it back to previous styles I have used for various nodes and relationships. For example, the nodes labelled "Country" which were styled in red change to green which I must have set previously sometime.
I also tried overwriting the styles with the following contents in a grass file to reset styles of all nodes and relationships but many of the nodes and relationships are still styled differently.
node {
diameter: 50px;
color: #A5ABB6;
border-color: #9AA1AC;
border-width: 2px;
text-color-internal: #FFFFFF;
font-size: 10px;
}
relationship {
color: #A5ABB6;
shaft-width: 1px;
font-size: 8px;
padding: 3px;
text-color-external: #000000;
text-color-internal: #FFFFFF;
caption: "<type>";
}
