Spectra is an ongoing international collaboration between Ria Rajan and Sofy Yuditskaya. As Spectra, our work centers around participatory and installation work, exploring the themes of light, visuals, colour, optics and sound. Ria Rajan (@riafish) is a visual artist and designer whose work spans across mediums both analog and digital, including drawing, painting, image making, material and sculptural explorations and interventions in spaces. Sofy Yuditskaya (@horusVacui) is a media artist and educator working with video, interactivity, projections, code, paper, and salvaged material. Her performances enact and reframe hegemonies, she works with materials that exemplify our deep entanglement with petro-culture.
