Reversability of Xor'd Values In Hash? This may be a dumb question so please forgive me if so, but is a hash function considered one-way even if you have half of an xor'd value?

For example say I have the values R and C, both are randomly generated and the same length as the output of the hashing function H, but while R is known C should not be given only R and h below:

h = H(C⊕R)


Is there any scenario in which you could determine C from h and R or which might reduce the difficulty of brute forcing C in this format to a level you would have to worry about?
Since both values are randomly generated, no, there are no scenarios in which you could determine C from h and R or where your ability to brute force C is made easier by having this information as opposed to just having h.
