I introduce the spatial curvature effects inside the formalism of Relative Locality as a non-commutative structure of the momentum space in agreement with the very well known concepts of Quantum Groups. This gives a natural red-shift effect in agreement with an extended version of the Generalized Uncertainty Principle (GUP) and in agreement with the standard notions of curvature inside General Relativity. I then introduce the concept of Relative Co-locality as a reinterpretation of the usual notions of spacetime curvature. From this redefinition, I obtain the momentum space curvature effects as a non-commutativity in position space. This introduce a natural blue-shift effect in agreement with the extended version of GUP. Both effects, Relative locality and Co-locality are dual each other inside the formalism of quantum groups $SU_q(n)$ symmetric Heisenberg algebras and their q-Bargmann Fock representations. When Relative locality and Co-locality are introduced, the q-deformation parameter takes the form $q\approx 1+\sqrt{ \frac{ \vert p\vert \vert x\vert}{ r_\Lambda m_{ pl}}}$ with the spatial curvature effects in Relative Locality appearing like $\Delta X\approx \frac{ \vert x\vert}{ m_{ pl}}\Delta P$ and the momentum curvature effects in Relative Co-locality appearing like $\Delta P\approx \frac{ \vert p\vert}{ r_\Lambda}\Delta X$, where $r_\Lambda=\frac{ 1}{ \sqrt{ \Lambda}}$ is the scale defined by the Cosmological Constant $\Lambda$, $m_{ pl}$ is the Planck mass and $\Delta X/\Delta P$ is a scale of position/momentum or time/energy associated with the event, p and x are the momentum and position of the observer relative to the event.
