1. A method, comprising:
receiving, via one or more processors, colorimetric data of a field component, wherein the colorimetric data corresponds to a portion of the field component or an integrity of a surface of the field component;
determining, via the one or more processors, a color value associated with the surface at a first time period;
retrieving, via the one or more processors, trend data indicating relationships between a plurality of color values and a plurality of conditions corresponding to the field component, and wherein the trend data comprises a colorimetric profile having at least a first portion with a positive slope, an intermediate point, and a second portion with a negative slope;
receiving, via the one or more processors, a previous color value associated with the surface at a second time period that is before the first time period;
determining, via the one or more processors, that the color value corresponds to the first portion, the intermediate point, or the second portion based on the previous color value and the colorimetric profile;
determining, via the one or more processors, a condition of the plurality of conditions corresponding to the field component based on the color value corresponding to the first portion, the intermediate point, or the second portion;
generating, via the one or more processors, a condition output based on the determined condition of the field component; and
outputting, via the one or more processors, a control signal based on the condition output, wherein the control signal is configured to adjust operation of a valve of the field component, a drill of the field component, or both based on the condition output.
