Also please check for variant_to_nscolor() return value.

Thanks, Nikolay. Sorry for my late reply.
I've checked the previous code in htmlbody.c, and found such code

385 static HRESULT WINAPI HTMLBodyElement_put_bgColor(IHTMLBodyElement
*iface, VARIANT v)
386 {
387     HTMLBodyElement *This = impl_from_IHTMLBodyElement(iface);
388     nsAString strColor;
389     nsresult nsres;
390
391     TRACE("(%p)->(%s)\n", This, debugstr_variant(&v));
392
393     if(!variant_to_nscolor(&v, &strColor))
394         return S_OK;
395
396     nsres = nsIDOMHTMLBodyElement_SetBgColor(This->nsbody, &strColor);
397     nsAString_Finish(&strColor);
398     if(NS_FAILED(nsres))
399         ERR("SetBgColor failed: %08x\n", nsres);
400
401     return S_OK;
402 }

So when variant_to_nscolor failed (because VARIANT is invalid), wine
would ignore it,
and return S_OK. Maybe return E_FAIL is better?

Also, in variant_to_nscolor, the return value of nsAString_Init is
ignored. Is it good?
Or should I write a patch to fix it?

Thank you.
