How to Add a Serial Color Node in DaVinci Resolve (Alt+S / Option+S)

Alt+S (Option+S on Mac) adds a new serial node to the current clip's node graph in the Color page, the fundamental action behind Resolve's node-based approach to color grading, where a look is built from multiple discrete, chained adjustment steps rather than one flat panel of sliders. **Why serial nodes specifically**: a serial node connects directly after the previously selected node in the chain, meaning its adjustments apply to the output of everything before it — a natural way to build a grade in logical layered steps, such as correcting exposure in the first node, adjusting white balance in a second, then applying a stylistic color look in a third, each working on top of the previous node's already-adjusted image. **Other node types exist alongside serial**: parallel nodes (which apply to the same input image independently and then combine, rather than one feeding into the next) and layer nodes (which composite based on masks or keys) serve different structural purposes, each with their own toolbar buttons and shortcuts, but serial is the default and most commonly used starting point for most grading work. **Isolating adjustments for easier revision**: because each node's settings are independently toggleable (clicking its enable/disable button) and independently resettable (Shift+D resets just that node), building a grade across several serial nodes rather than cramming everything into one makes it far easier to isolate and adjust a single conceptual step later without disturbing the others — toggling off just the stylistic-look node to compare against the corrected-but-unstylized image, for instance. **Related shortcuts**: Shift+D to reset a selected node's adjustments back to neutral without deleting it, and Ctrl+Shift+G (Cmd+Shift+G) to grab a still of the current graded result to the Gallery for reference or reuse on other clips. **Naming nodes for clarity**: double-clicking a node's label lets you rename it from a generic number to something descriptive like 'Exposure' or 'Skin Tone,' which pays off considerably once a grade accumulates several nodes and you're trying to quickly locate the specific step responsible for a particular look, especially when handing the project off to another colorist. **Parallel nodes as an alternative structure**: Alt+P (Option+P) creates a parallel node instead of a serial one, branching off the same input and combining results back together rather than chaining sequentially — useful for isolating a correction to a specific tonal range (shadows or highlights) via a separate branch, then recombining, rather than layering that isolation logic into one serial node with complex internal qualifiers. **Toggling a node on and off for comparison**: every node includes an enable/disable toggle directly in the node graph, letting you instantly compare the image with and without that specific step's contribution — a fast way to judge whether a particular correction is actually improving the shot before committing to keeping it in the final grade. Building the habit of naming and organizing nodes deliberately pays off considerably on any grade complex enough to require revisiting weeks or months later. **Copying a node's grade to another clip**: once a node chain looks right on one clip, right-clicking it and choosing to copy the grade, then pasting onto another selected clip or a whole group of clips via Gallery stills applies the identical node structure and settings elsewhere, avoiding the need to rebuild an equivalent chain of serial nodes by hand on every similar shot in a scene.
