If I understand correctly, you are looking for something like this?
It’s a Tampermonkey script I wrote which removes the black border around the white stones, giving them a “flat” look against a plain background
relevant code
This is the code, just for modifying the border, not changing the background colors… not tested
You can set the color at line ctx.strokeStyle = color;
to some other hex value, or play around with line width
(function() {
function setup() {
console.log("[ogs border] setting up");
// custom place stone function for flat edges
var placeStoneFn = function(color) {
return function(ctx, shadow_ctx, stone, cx, cy, radius) {
let lineWidth = radius * 0.10;
if (lineWidth < 0.3) {
lineWidth = 0;
}
ctx.fillStyle = color;
ctx.strokeStyle = color; // changed to use same color as stone, instead of line color
if (lineWidth > 0) {
ctx.lineWidth = lineWidth;
}
ctx.beginPath();
ctx.arc(cx, cy, radius - lineWidth / 2, 0.001, 2 * Math.PI, false); /* 0.001 to workaround fucked up chrome bug */
if (lineWidth > 0) {
ctx.stroke();
}
ctx.fill();
};
};
GoThemes.white.Plain.prototype.placeWhiteStone = placeStoneFn(white);
GoThemes.black.Plain.prototype.placeBlackStone = placeStoneFn(black);
// click the theme selector which will trigger a redraw
document.querySelector("div.theme-set div.selector").click();
console.log("[ogs border] done");
};
// set up the mutation observer
// altho this should be installed with @run-at idle, I still saw the code run prior to these globals being available, so just watch the page for updates until they are present
var observer = new MutationObserver(function (mutations, me) {
if (typeof data !== "undefined" && typeof GoThemes !== "undefined") {
setup();
me.disconnect(); // stop observing
} else {
console.log("[ogs no border] data or GoThemes not found, waiting...");
}
});
// start observing
observer.observe(document, {
childList: true,
subtree: true
});
})();
